c, 14d are recesses 16a, 16b, 16c, 16
The rotation of the holding members 14a, 14b, 14c, 14d is set by setting pins 17a, 17b which are provided in the recessed portion and fixed to a frame (not shown). Holding members 14a, 14b, 1

5 and 26.

Next, the operation will be explained.

For example, when the drive unit 1 is rotated clockwise about the driven shaft 2 in the figure, the drive pin 4 on the left side in the figure is moved to the left side of the elastic member 5 due to the clockwise rotation of the drive plate 3. Touch it and push it to the right. On the other hand, the right side of the elastic member 5 is in contact with the setting pin 8 on the right side of the figure that is fixed on the driven plate 7, and the driven plate 7 passes through the driven shaft 2, the locking plate 10, and the locking pin 11. Since it is held by the holding member 14c,
The elastic member 5 stores operating energy, and the stored power increases as the drive plate 3 rotates. The rotation continues further, and when the elastic member 15 reaches the end of its energy storage and sufficient driving force is obtained, the release member 19 that cooperates with the drive plate 3 engages with the other end 18c of the holding member 14c. Then, by pushing this down, the holding member 14c rotates clockwise around the pivot pin 13. As a result, one end 15c of the holding member 14c
The locking pin 11 is disengaged, the right side of the elastic member 5 is released from being held, and the driven shaft 2 is driven by the energy stored in the elastic member 5. This operation causes the drive lever 21 to rotate clockwise via the main shaft 20 connected to the driven shaft 2, operating the movable contact 23 via the insulating rod 22, and contacting the fixed contact 25 to fix it. From terminal 24 to fixed contact 25
energization is performed. The contact opening operation is performed by rotating the drive unit 1 counterclockwise from this state, and the connection to the fixed contact 26 is the same except that it is performed reversibly.

[Problem that the invention seeks to solve]

Since the conventional operating device is configured as described above, it is not possible to maintain the state in which energy is stored in the elastic member by the drive unit, and therefore it is not possible to perform remote control to perform immediate operation. There was a problem. In addition, when multiple of these operating devices are incorporated into a multi-circuit switchgear and operated, it is more difficult to retain energy, and it is difficult to release only the stored energy without operating the contacts. Furthermore, it is difficult to remotely control a multi-circuit switch that requires multi-position operation, which is a problem.

This invention was made in view of the above-mentioned problems, and it is possible to lock a drive unit that stores energy in an elastic member and hold it in the stored state, and release the retained state by operating a contact point. The object of the present invention is to obtain an operating device that has a remote control function that can be performed without having to use the remote controller.

[Means for solving problems]

The operating device according to the present invention includes a drive unit that operates to store energy in an elastic member, and a locking member that is pivoted to the drive unit, and a holding member that engages with the locking member at the operating position of the drive unit. wherein the locking member and the holding member are engaged and disengaged via an engagement release member fixed to the locking member, and the engagement release member is operated prior to operation of the drive unit. The device is characterized in that it further includes an operation section for operating the drive section.

[Effect]

The engagement and disengagement operations between the locking member and the holding member of the drive section of the operating device according to the present invention are performed by the operation of the operating member so that the disengagement member is caused to precede the operation of the drive section. Accordingly, the elastic member can be easily charged and released.

Only the operating lever 55 rotates until it comes into contact with the inner periphery of the guide hole 29a, and as shown in FIG.
8 kicks the drive pin 52 and rotates the disengagement member 51 counterclockwise in the figure via the locking pin 50 pivoted on the drive plate 29. When the disengagement member 51 rotates, it pushes the lock pin 49b of the holding lever 48b and rotates the holding lever 48b clockwise.
The engagement between the holding lever 48b and the locking pin 50 is released (FIG. 2). Next, since the holding of the locking pin 50 by the holding lever 48b is released, the operating pin 56 comes into contact with the guide hole 29a and rotates the driving plate 29 clockwise by the subsequent rotation of the operating lever 55. One end of the elastic member 31 is rotated by a drive pin 30 fixed to the elastic member 29. At this time, as shown in FIG. 1, the driven-side locking portion 35 is held as it is by the locking pin 37 engaging with the one end 41b of the first latch 40b and being prevented from rotating.

rotates clockwise. As a result, driven shaft 28
, the main shaft 20 is also rotated, and the drive lever 2 is rotated.
1, the movable contact 23 is driven through the insulating rod 22, and a circuit from the fixed terminal 24 to the fixed contact 25 is formed to conduct electricity. On the other hand, if you want to release only the energy stored in the elastic member 31 in order to reverse the operation of the movable contact 23 from the state where the elastic member 31 has already been stored (FIG. 3), for example, a ratchet mechanism, etc. When the operating shaft 57 is rotated counterclockwise from the position shown in FIG.

The engagement release member 51 pushes the locking pin 49a through the locking pin 49a, rotates the holding lever 48a counterclockwise, and releases the engagement of the holding lever 48a with the locking pin 50. As a result, the drive plate 29 is released by the stored force applied to the drive pin 30 by the elastic member 31, and rotated to the open state position of the elastic member 31 where the locking pin 50 and the holding lever 48c engage. , releases energy and waits until the next operation.

In the above embodiment, a structure is shown in which holding members of the driving part are provided on both sides and the power can be held in both directions, but the second latches 45a, 45b, 45c, and
The lengths of the tabs 47a, 47b, 47c, and 47d are changed, and the opening member 19 similar to the conventional one is attached to the drive plate 29.
By providing this, it is possible to arbitrarily select a combination of direct operation and remote control.

〔Effect of the invention〕

As described above, according to the present invention, the holding part that holds the drive part, the locking member that engages with the holding part, and the engagement release member that releases the engagement are provided, and the release of these parts is controlled by the operation of the drive part. Since the configuration is configured so that the operation is performed in advance using the operating member, there is an effect that remote control of a multi-circuit switch that requires more stable operation and multi-position operation can be obtained at low cost and with high accuracy.
