Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a safety device for the door of an amusement machine, and more particularly to a locking device for the door of a cantilever-tilt type swinging amusement machine.

(Prior art) Some amusement machines installed at amusement parks, etc., carry passengers and lift them to a high place, rotate them at high speed, use centrifugal force from turning, or pull them to a high place. There are vehicles that fly up and use potential energy to perform 360-degree somersaults, so the doors of these vehicles must be locked for safety reasons.

However, because the lock is forced to lock on all vehicles at the same time by remote control, conventional locks cannot be used in the event of a cylinder failure or power outage.
It has the disadvantage that it cannot be unlocked.

(Problems to be solved by the invention) The purpose of the invention is to provide a safety device for the door of an amusement machine that can release the lock and open the door even if the lock cylinder malfunctions or there is a power outage. It is.

(Means for Solving the Problems) In the amusement machine of the present invention, the door is opened and closed by the first cylinder, and the door is closed by locking it with a hook at the tip, and the hook is attached to the shaft. It is pivoted and has a handle, the tip is biased by a spring, and the rear end is brought into contact with a second cylinder, so that when the second cylinder is contracted, the hook can be locked by the spring, By pulling the handle against the spring, the hook can be engaged and disengaged without extending the second cylinder, thereby achieving the above object.

(Function) The door safety device of the present invention is not limited to cantilever-tilt type rotating game machines, but can also be used to release the safety of door locks of various rotary game machines, jet coasters, etc. can.

(Example) An example of the present invention will be described below based on the accompanying drawings.

1 is a vehicle used in a cantilevered swinging amusement machine. When a person gets on the space capsule vehicle 2, the first cylinder 4 is extended from the position of the dotted line with the door 3. Close it by coming to the position of the solid line.

The door is closed by engaging and locking the hook 5 on the top end 3a of the door 3. The hook 5 is rotatably attached to the shaft 6, and has a locking pawl 7 at the tip, a spring 8 on the front tip side, and a handle 9 projecting at a right angle. has
A second cylinder 11 is attached to the flange 10 that protrudes from the rear end.
The tips of the two are in contact with each other. Therefore, when opening and closing the door 3 using the first cylinder 4, the second cylinder 1
1 is extended and the hook 5 is at the position indicated by the dotted line. When the second cylinder 11 is absorbed, the tip of the hook 5, which is pivotally connected to the shaft 6 by the spring 8, comes down as shown by the solid line, and the locking claw 7 is attached to the door 3. It is latched to the leading edge 3a and locked. However, if the handle 9 of the hook 5, which is located on the rear side of the upper exterior of the door 3 and is normally not touched by passengers, is pulled in the direction of arrow A against the spring 8, the second cylinder 11 will not be extended. In both cases, the hook 5 can be raised to the position indicated by the dashed line.

(Effects of the Invention) The safety device for the door of the amusement machine of the present invention can release the lock and open the door even in the event of a lock cylinder failure or power outage.

Furthermore, since the handle is provided on the rear side above the outside of the door of the vehicle, it is provided in a safe position where passengers do not normally touch it, and it can be used in a wide variety of amusement machines.

Claims (1)

[Claims for Utility Model Registration] 1. The door is opened and closed by the first cylinder, and the door is closed by locking it with a hook at its tip.The hook is pivotally attached to a shaft and has a handle at its tip. A spring is applied to the spring, and a second cylinder is brought into contact with the rear end, so that when the second cylinder is contracted, the hook can be locked by the spring, and the handle can be pulled against the spring. For example, a safety device for a door of an amusement machine is characterized in that the hook can be engaged and disengaged without extending the second cylinder. 2. The safety device for a door of an amusement machine according to claim 1, wherein the handle is provided on the upper rear side of the door. 3. The safety device for the door of a game machine according to claim 1, wherein the game machine is a rotating game machine of a cantilever type.
