Description

[Detailed Description of the Invention] This invention relates to a locking device for a gate bar in a gate device installed at an entrance/exit of a parking lot and controlling the passage of vehicles.

As this type of locking device, one is known that detects the tip of the gate bar and locks the gate bar based on this detection signal.

However, this device requires a detection device at the tip of the gate bar, making the overall configuration complicated.

This invention was made in view of the above-mentioned circumstances, and aims to provide a device that is extremely simple in construction and can be locked reliably.

Embodiments of this invention will be described in detail below with reference to the drawings.

The first diagram shows the entire gate device installed at the entrance/exit of a parking lot.

The base end of the gate bar 1 is pivotally connected to the opening/closing machine 2, and the gate bar 1 is rotated by the opening/closing machine 2 between a nearly vertical state and a horizontal state.

When this gate bar 1 is in a horizontal state, the gate is closed, and at this time, the tip of the gate bar 1 is locked by a locking device 3.

Details of the locking device 3 are shown in FIGS. 2 and 3.

A recess 4 is formed in the upper part of the locking device 3, into which the tip of the gate bar 1 enters from above.

On one side of the recess 4, a closing lever 7 formed in a V-shape and consisting of a closing piece 5 and an operating piece 6 is pivotally mounted at its center by a pivot shaft 8.

The plane on which the closing lever 7 rotates is perpendicular to the horizontal gate bar 1.

The closing lever 7 is normally urged by a return spring 9 to be in the open position (the position shown by the solid line in FIG. 2).

At this time, the closing piece 5 abuts against the stopper 10 and is maintained in a vertical position, and the actuating piece 6 is in a position across the recess 4.

On the other side of the recess 4, a hook (locking member) 11 is provided with a protrusion (locking part) 12 that protrudes onto the travel path of the tip of each piece 5, 6 of the closing lever 7, and is held by a support shaft 13. It is pivoted almost at the midpoint.

The pivot 8 and the support shaft 13 are arranged in a perpendicular state,
The planes in which the closing lever 7 and the hook 11 pivot are also orthogonal.

This hook 11 is biased by a tension spring 14, and a portion thereof abuts against a stopper 15, thereby being held in a vertical position.

In this state, the protrusion 12 protrudes onto the movement path of the closing lever 7.

The upper side of the protrusion 12 is inclined downward toward the tip (this is indicated by 12a (cam surface)),
The lower side is horizontal and serves as a locking portion 12b.

Furthermore, a rod 16a of a solenoid 16 for opening the gate is connected to the upper part of the hook 11.

This solenoid 16 is actuated by the gate opening signal and pulls the upper part of the hook 11 to move the protrusion 12 out of the movement path of the closing lever 7.

When a gate close signal is input while the gate bar 1 is in an open state, the opening/closing machine 2 is activated and the gate bar 1 rotates to a horizontal position.

When the tip of the gate bar 1 hits the operating piece 6 of the closing lever 7 from above, the closing lever 7 moves against the spring 9 from the open position to the closed position (the position shown by the chain line in FIG. 2) due to the gate bar 1's own weight and rotational force. ).

The tip of the actuating piece 6 first touches the inclined side 1 of the protrusion 12 of the hook 11.
2a, this protrusion 12 moves back against the spring 14 and allows the actuation piece 6 to pass through.

When the closure piece 5 passes through the location of the protrusion 12, the protrusion 12 also retreats from the movement path of the closure piece 5.

When the closing lever 7 passes through the protrusion 12, the hook 11 returns to its original position and the protrusion 12 protrudes onto the movement path of the closing lever 7.

As mentioned above, the lower side of the protrusion 12 is horizontal, and the locking part 12
b, the closing lever 7 that has reached the lower side of the protrusion 12 is maintained at this closed position without returning to its original open position.

Since the tip of the gate bar 1 is located below the closing piece 5, it is completely locked by the closing piece 5 and the projection 12 of the hook 11.

When the gate opening signal is sent, the solenoid 16 is activated and the upper part of the hook 11 is pulled against the force of the spring 14, and the protrusion 12 retreats from the movement path of the closing lever 7, so that the closing piece 5 and The engagement with the projection 12 is released and the closing lever 7 tends to return to the open position under the force of the spring 9.

Further, the opening/closing machine 2 is driven by the gate opening signal, and the tip of the gate bar 1 rotates upward, so that the gate bar 1 comes out of the recess 4 upward as the closing lever 7 rotates.

As described above, the gate bar locking device of this invention is extremely simple in construction because the gate bar acts directly on the closing lever and automatically locks the gate bar without requiring a gate bar detection device. .

Further, since the closing lever is engaged with the lock portion of the locking member, the locking of the closing lever is reliable.

Also, since there is no need to provide a locking mechanism on the gate bar,
It can be applied to gate bars of various shapes and thicknesses.

Furthermore, since the support member may be provided near the position where the tip end of the gate bar reaches when the gate bar is closed, the installation position of the support member can be selected relatively freely.

Further, since an electric release device for retracting the lock portion of the lock member is provided, the operation for retracting the lock portion is simple, and the lock portion can be retracted by remote control.
