Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a safety band device installed in the seat of a ride that rotates in the air, such as a ride coaster installed in an amusement park or the like, and other various types of amusement rides.

Conventionally, there are various safety bands of this type, but none of them are excellent in holding the upper body of a seated person firmly against the seat, and furthermore, there is a defect in the mechanism for locking the held state.

This idea was devised in view of the above circumstances, and its purpose is to create a system that can be opened and closed to the left and right of the seated person, and when closed, extends from both shoulders of the seated person, along the chest and to the flanks (・The upper body can be held securely against the seat, and the lock is extremely reliable.
The object of the present invention is to provide an extremely simple and highly safe device that cannot be opened when locked, but can be closed freely, and can be easily closed after locking, even though passengers tend to be late in closing the door.

An embodiment of this invention will be described below with reference to the drawings.

1 in the figure is a device box installed on the back of the backrest of seat A.
A pair of left and right rotating shafts 2, 3 are mounted on the left and right sides of the equipment box 1, slightly inclined to each other on a vertical plane in the shape of a . It is rotatably mounted.

Both rotating shafts 2 and 3 are interlocked by an interlocking mechanism 5 so that they rotate simultaneously in opposite directions.

The interlocking mechanism 5 includes a lever 6 that projects forward from the middle part of the rotating shaft 2 on the left side of the drawing, a lever 7 that projects rearward from the middle part of the rotating shaft 3 on the right side of the drawing, and both levers 6. It consists of a Rondo 9 whose both ends are pivotally connected to the tips of the shafts 7 and 7 through link ball joints 8 and 8 respectively, and when one rotating shaft 2 rotates clockwise, the other rotating shaft 3 simultaneously rotates counterclockwise. Make it rotate (・ru.

The upper ends of the left and right rotating shafts 2, 3 extend above the device box 1, respectively, and the mounting tubes 10, 10 are fitted to the upper end extensions 2a, 3a, thereby connecting the rotating shafts 2, 3. A pair of left and right body restraining members 11, 1 move in unison.
1 is installed protrudingly.

These left and right body restraining members 11, 11 are metal round pipes 11.
The cushion cover 11b covers the outer periphery of the cushion cover 11b, and is bent into a substantially U-shape to cover the upper body of the seated person H from both shoulders of the seated person H along the front of the chest to both flanks. It has a shape that is held down against the backrest of seat A as if it were held in place, and can be rotated freely around both rotating shafts 2 and 3 as fulcrums by the operation of seated person B, so that it can open outward to the left and right (or move inward). Now I can close it (・ru.

Further, a cylinder lever 12 is provided at the lower end of one of the rotating shafts 2 to project forward, and the tip of a piston rod 13a of a long cylinder 13 is pivotally connected to the tip of the lever 12.

This lock cylinder 13 is a hydraulic cylinder that is swingably attached to a bracket lift 14, 14 fixedly installed in the equipment box 1 via a pin 15, and a fluid pressure circuit (hydraulic circuit) is installed at both ends of the cylinder chamber. 16 flow pipes 16a
, 16bY, pressure oil at a constant pressure is always conducted from the oil supply port 16c, and an on-off valve 1T is interposed in one of the flow pipes 16b of the fluid pressure circuit 16, and in parallel with the on-off valve 17. A check valve 18 is provided via the bypass flow path pipe 16d.

Therefore, the functions of the safety band device of this invention are as follows.
First, when the seated person B sits on the seat, the opening/closing valve 11 is opened so that the rotating shafts 2 and 3 as well as the body restraining members 11 and 11 are free to rotate. When the holding member 11 is grasped and pushed outward, both the valve body holding members 11, 1.1 are rotated together with the rotating shafts 2, 3, respectively, via the interlocking mechanism 5 so as to open outwardly to the left and right.

At this time, since the rotating shafts 2 and 3 are tilted from top to bottom in a 71 shape, the holding members 11.degree.

Therefore, seated person B can sit on seat A, and when seated person B rotates both valve body suppressing members IL11v toward the front and closes each other after sitting, seated person B's upper body moves from both shoulders along the front of the chest. Both valve body restraining members 11, 41 extend over the flanks.
I was pinned down to seat A as if being grabbed by a man.

When the operator in this state closes the on-off valve 17, the lock cylinder 13 prevents the rotation of both rotating shafts 2 and 3, thereby preventing both valve body restraining members 1. ．． 1 and 1.1 are also prevented from rotating and become locked, and both valve body restraining member members 11 and 1
1 does not unnecessarily open outward to the left and right, the upper body of the seated person B is securely fixed, and safety during driving is ensured.

Here, even if the seated person B performs the locking operation by closing the opening/closing valve 17 before closing both the valve body suppressing members IL11, the both valve body suppressing members 11, 11 will not rotate in the opening direction. Although the movement is blocked, the check valve 18 allows for free rotation in the closing direction, so the seated person B can easily close both valve body restraining members 11°11 even after the above-mentioned locking. can be operated to protect one's own safety.

In the above embodiment, a hydraulic cylinder is used as the lock cylinder 13, but the lock cylinder 13 is not limited to this, and an air cylinder may also be used. Although only the part was fixed,
As shown in the imaginary line in FIG. 1, the lower end of the rotating shaft may be extended, and the lower end of the vibrator 11a of the restraining member 11 may be extended and fixed thereto to be supported at both upper and lower ends.

Since this invention has been developed as described in detail above, it has a simple structure in which both the valve body restraining members can be opened and closed on the left and right sides of the seated person, but when the restraining members are closed, the valve body restraining members can be opened and closed from both shoulders of the seated person to the chest. It is possible to hold the upper half of the body firmly against the seat by holding it over both side membranes along the front, and the locking of both restraining members is reliable when closed. Sometimes both retaining members cannot be opened (・
can be closed freely by the check valve, and this allows passengers who are late in closing both restraining members to close both restraining members by themselves after locking to protect their own safety. It is extremely simple and extremely safe.
