Hereinafter, the operation of the bidirectional locking device 100 according to an embodiment of the present invention configured as described above will be described with reference to FIGS. 8 and 9.

8 is a view for explaining the operation of the bidirectional locking device 100 using a double latch according to an embodiment of the present invention, Figure 9 is a bidirectional locking device using a double latch according to an embodiment of the present invention. It is a figure for demonstrating back-lash prevention in (100).

The bidirectional locking device 100 is installed at one side of the base frame 10, and the first and second fixing brackets 210 and 220 are the first frame 21 and the moving frame 20 of the moving frame 20. Are respectively installed on the second frames 22 of the.

On the other hand, when the moving frame 20 is switched from the first posture to the second posture, the first binding shaft 200 enters and locks in the first binding shaft pocket 111a of the bidirectional locking device 100, and the moving frame ( When 20) is switched from the second posture to the first posture, the second engagement shaft 200a enters and locks in the second engagement shaft pocket 111b of the bidirectional locking device 100, wherein the first and second engagement Since the operations in which the shafts 200 and 200a are locked or unlocked are similar, the overlapping description will be omitted and the operation of locking or unlocking the first binding shaft 200 will be described.

As shown in FIG. 8A, the bidirectional locking device 100 stands by with the first and second shaft pockets 124a and 124b on both sides of the latch wheel 120 open. The second leading latches 131a and 131b and the first and second trailing latches 132a and 132b are pushed toward the latch wheel 120.

Subsequently, as shown in FIG. 8B, the latch wheel 120 is forwarded in the direction in which the first binding shaft 200 enters while the first binding shaft 200 enters the first shaft pocket 124a. Is rotated, the other part of the first binding shaft 200 enters the first binding shaft pocket 111a of the first and second bodies 110a and 110b, and the first and second preceding latches 131a. 131b and the first and second trailing latches 132a and 132b are pushed in response to the rotation of the latch wheel 120, and the latch gears are sequentially engaged to prevent reverse rotation of the latch wheel 120.

Subsequently, as shown in (c) of FIG. 8, when the first engagement shaft 200 is completed, the first engagement shaft 200 includes the first shaft pocket 124a, the first and the first shaft pockets of the latch wheel 120. Locked while being locked in the first engagement shaft pocket 111a of the two bodies 110a and 110b, the first leading latch 131a and the first trailing latch 132a prevent the latch wheel 120 from being arbitrarily reversed. Done.

On the other hand, the second leading latch 131b and the second trailing latch 132b are in contact with the latch wheel outer diameter portion 128 of the latch wheel 120, and the idle state is maintained.

In addition, the first stopper 125a of the latch wheel 120 is accommodated in the first stopper pocket 114a of the first and second bodies 110a and 110b to prevent further rotation of the latch wheel 120. do.

On the other hand, when the attitude change of the moving frame 20 is to be performed, the first binding shaft 200 should be detached from the bidirectional locking device 100, and at this time, a command according to the attitude change of the moving frame 20 is issued. As shown in FIG. 7, the actuator 160 acts to load the rod 162 to seesaw the lever unit 150, and the lever unit 150 pressurizes the first and second latch rods 134a and 134b. The first preceding latch 131a and the first trailing latch 132a are spaced apart from the latch wheel 120 to freely rotate the latch wheel 120.

That is, as the rotation of the latch wheel 120 becomes free, the moving frame 20 changes its posture, and thus the first binding shaft 200 is released from the bidirectional lock device 100, and then the latch wheel 120 is initialized. After returning to the state, the first binding shaft 200 or the second binding shaft 200a is allowed to enter in a state where it is possible to enter.

On the other hand, when the first and second latches 131a and 132a are unlocked by the latch wheel 120, there is a time difference between the movements of the first and second latches 131a and 132a. This may occur with reference to the accompanying drawings, FIGS. 7 and 9.

Even if the lever unit 150 presses the first preceding latch 131a to move the first preceding latch 131a, the first protruding key 136a is provided inside the first and second key pockets 135a and 135b. Since there is a gap b, the first trailing latch 131a does not move until the inner side surfaces of the first protruding key 136a and the first and second key pockets 135a and 135b touch each other.

That is, even if the latch gear of the first preceding latch 131a is immediately released from the latch pocket 126 of the latch wheel 120, the first trailing latch 132a is positioned in the latch pocket 126 so that the latch wheel 120 may be located. It is possible to prevent the rapid rotation of the.

In addition, the latch gears of the first and second preceding latches 131a and 131b and the first and second trailing latches 132a and 132b contact the latch wheel outer diameter 128 of the latch wheel 120. Eventually, the contact points are made at four points, and these contacts are made sequentially and continuously to remove backlash that may occur when the latch wheel 120 is reversed, and further, the moving frame 20 is removed. You can turn more stable.

The first and second preceding latches 131a and 131b, the aforementioned first and second trailing latches 132a and 132b, and the latch wheel 120 described above may be caused by various causes such as machining errors and wear. ), Even though the meshing is not smoothly engaged, it is possible to smoothly implement the anti-rotation action of the latch wheel 120 by contacting at four points.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. will be.

It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.

The bidirectional locking device using the double latch according to the present invention can be used to secure the moving structure to the fixed structure.
