Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an operating device, and in particular to an operating device that stores operating energy in an elastic member using a link mechanism in order to operate a multi-circuit switch, etc., and releases it. Therefore, it relates to an operating device that controls the operation of a switch or the like.

[Prior art]

Conventionally, this type of operating device has generally had two positions, so for a switch that requires three positions, for example, a position converter is added to the two-position operating device, and the two devices are combined. I tried to adapt it to the 3rd position.

With such a configuration, the output section of the operating device is one unit, and when interlocking with a multi-circuit switch via a position conversion device added to this, the operating characteristics of each switch must be the same. Must be. Before operating the operating device, it is necessary to dry the position converter for selecting the switch, and it is also required to provide a locking device between these devices to prevent erroneous operation, so the device is complicated. However, it had the disadvantage of being large and lacking in practicality.

Furthermore, since both the operating device and the converter must be operated, when using an electrical control system, it is necessary to coordinate with a manual operating system, which also has the disadvantage of being difficult.

Furthermore, since the operating output is constant, various problems inevitably arise when combinations of switches with different characteristics are used.

[Summary of the invention]

This invention was made in view of the above-mentioned drawbacks of the conventional products, and has an excellent structure that has a simple structure, can be held in multiple positions, and can adjust the output with one elastic member for each position. The purpose of providing an operating device is to provide a holding member that holds a driven shaft at the operating position (holding position) of each switch for one position of the operating device, and a driven part having a driven shaft and a driving shaft. an elastic member is interposed between the drive unit including the
Energy is stored in the elastic member by the drive shaft, and near the end of rotation of the drive shaft for energy storage, the holding member is released by an engaging member that cooperates with the drive shaft, and the driven shaft is stored in the elastic member. The present invention provides an operating device that has a structure that reversibly performs the force and release operations, has a simple structure by integrating multiple positions, and can adjust the output with one elastic member for each position.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

1 and 2 show an embodiment of a three-position operating device, and as shown in the figure, a drive unit 1 includes a drive plate 3 rotatably fitted on an extension of a driven shaft 2, and a drive plate 3 mounted on the drive plate 3. It is composed of a pair of fixed driving pins 4, and the driving pins 4 are in contact with both ends of the elastic member 5 mounted on the shaft portion 3a of the driving plate 3, that is, the operation spring, and are arranged so as to sandwich the elastic member 5. position on the drive plate 3. The driven part 6 consists of a driven shaft 2, a driven plate 7 fixed to the driven shaft 2, and a pair of setting pins 8 fixed to the driven plate. are arranged on both sides of this member to set the In this way, the elastic members 5 and the driving parts 1 are fitted together via the driven shaft 2.
and the driven part 6. The locking part 9 provided on the driven shaft 2 consists of a locking plate 10 fixed to the driven shaft 2 and a locking pin, that is, a locking member 11 attached to the tip of this plate. The member 11 is designed to be able to move on an arc-shaped movement locus (dotted chain line 110) centered on the driven shaft 2 as the driven shaft 2 rotates, but there is a fixed member that rotatably supports the driven shaft 2. A pivot pin 13 provided on the support portion 12 (FIG. 2) enables engagement with one end 15c of a rotatably supported holding member 14c. The holding member 14c has a recess 16c in which the setting pin 1 protrudes from the fixed support 12.
7, the rotation (swing) of the holding member 14c is set. One end 15c of the holding member 14c and the other end 18c are arranged so as to cooperate with the drive unit 1, for example, along a rotation locus (dotted chain line 19) of a release member 19 provided at one end of the drive plate 3, also centered on the driven shaft
0), and is engaged with the release member 19 by rotation of the drive plate 3, so that the holding member 14c can be rotated by a small angle clockwise in the figure. The holding member 14c is paired with another holding member 14b, and the holding member 14b is in a symmetrical position with respect to the holding member 14c with respect to the pin 13, one end 15b of which is on the movement trajectory of the locking member 11, and the other end 18b is in a position where it can engage with the release member 19. Further, in the illustrated example, the driving plate 3 and the driven plate 7 are symmetrical with respect to the line OB connecting the centers O and B of the driven shaft 2, so that the three positions A, B, and C are obtained, and the driving plate 3 and the driven plate 7 are symmetrical with respect to the line OB connecting the centers O and B of the driven shaft 2, 4,
The setting pins 8 are located symmetrically with respect to the line OB, and the pivot pins 13 that support the holding members 14c and 14b and the pivot pins 13 that are symmetrical with respect to the line OB are located on the holding member 1.
4a and 14d, and the holding member 14a, holding member 14c, and holding member 14d are symmetrical to the holding member 14b, so their explanation will be omitted.

For example, manually move the drive unit 1 from position B to position C in the figure.
To explain the effect when operating in position,
When the drive plate 3 is rotated clockwise in FIG. Since the elastic member 5 is held by the holding member 14c via the driven plate 7, the driven shaft 2, the locking plate 10, and the locking member 11, the elastic member 5 stores energy, and the stored force is transferred to the driving plate. It increases as the number 3 rotates. The rotation continues further, and when the elastic member 5 approaches the end of its energy storage and sufficient driving force is obtained, the release member 19 that cooperates with the drive plate 3 approaches the C position, and the other end of the holding member 14c 18c (see FIG. 3) and presses down to rotate the holding member 14c clockwise about the pivot pin 13.
The engagement between the one end 15c and the locking member 11 is disengaged, and the holding of the right side of the elastic member 5 is released, so that the driven shaft 2
is driven by the necessary driving force by the elastic member 5 (see FIG. 4). At position C, the locking member 11 engages with one end 15b of the holding member 14b, and a biasing member (not shown) counteracts the return force applied to the holding member 14b, causing the holding member 14b to move counterclockwise. When it is pushed up and passes the other end 15b, the holding member 14b returns and the locking member 11 is held at the other end 15b (see FIG. 5). The movement from position C to position B and the movement from position A to position B are reversible, and the movement from B to A can be changed from B to C by simply reversing the left and right sides.
It is exactly the same.

In the following, the members are shown in completely symmetrical shapes for each position of A, B, and C, but if you want to obtain the necessary driving force in various ways depending on the position and orientation,
Respectively corresponding holding members 14a, 14b, 14
If the release timing of the release member 19 is adjusted by changing the shape of the position at which the release member 19 presses down the other ends 18a, 18b, etc., the driving force, that is, the stored energy of the elastic member 5, can be reduced. It will be understood that forces can be changed.

In addition, in the above embodiment, a three-position type was explained, but for a larger number of positions, the points corresponding to the B position can be increased to B' and B'' and inserted between the A and C positions. Therefore, the same principle can be applied in an expanded manner.Furthermore, although the case where the locking member and the release member draw circular trajectories has been described, the same effect can be obtained when the driving part and the driven part take linear trajectories. Further, although the operation spring or elastic member is configured to store rotational force, it is also possible to use linear force storage by changing a part of the drive system.

〔Effect of the invention〕

As described above, according to the present invention, a pair of holding members are arranged symmetrically in order to hold the driven part at a required position, and at the end point of the spring storage movement of the driving part, the releasing member cooperates with the driving part. Since the structure is such that the holding member is actuated and the spring is released by the member,
An operating device that can operate in multiple positions can be produced with a simple configuration and at low cost, and has the effect of providing an operating device that is highly practical.
