PURPOSE:To adjust swivel angles of plural structure members such as a reflecting mirror simultaneously and accurately and also hold them by providing an eccentric driving device equipped with a link mechanism and a grooved cam, and swiveling and adjusting plural members simultaneously by one touch through the driving of the eccentric driving device. CONSTITUTION:When a handle 45 is operated and rotated by about 60 deg. until a ball 41 enters another storage hole 35, a driven pin 24, i.e. link plate is moved by several mm. by an eccentric cam 25, and consequently both base angles 6a and 6b rotate around a stepped screw 7 through a link 18. At this time, the base angles 6a and 6b rotate in the opposite directions and a right and a left reflecting mirror half body fitted thereto through support frames 13a and 14a, and 13b and 14b rotate to change optical axis directions of light reflected by the reflecting mirror.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device, and particularly to a one-touch operating device for a plurality of members, such as a reflector of a searchlight, whose turning angle must be simultaneously and accurately adjusted and maintained.

Conventionally, this type of operating device has been located behind the reflector and attached to the machine frame and the support frame of the reflector. The support frame of the reflector is pivotally supported by the upper and lower support shafts on the base of the searchlight body, and rotation around the support shaft is achieved by the bolts attached to the base of the light body being inserted into the control grooves of the support frame of the reflector. It was screwed into the fitted slide piece, and was tightened or loosened by tightening or loosening the bolt. However, in such a structure, since the distance from the support shaft to the support frame is relatively long, a large amount of movement of the front or slide piece is required to obtain the required turning angle of the reflector, resulting in a large operating device. Moreover, the structure was complicated.

In view of the above, an object of the present invention is to create an operating device with a simple structure that can simultaneously accurately adjust and hold the turning angles of a plurality of structural members such as a plurality of reflecting mirrors.

According to the present invention, the operating device, especially the operating device for adjusting the angle of the reflector of a searchlight, is composed of a link mechanism and an eccentric drive device, and by driving the eccentric drive device, a plurality of members can be accurately rotated and adjusted at the same time with a single touch. It is characterized by the following.

The present invention will be explained in detail based on the drawings.

1 to 4, a substrate 2 is fixed on the housing 1 and on the inner surface of the housing 1, and a seat plate 3 is placed on the substrate 2.
is fixed. A spring washer 4 and a flat washer 5 are attached to the seat plate 3.
The two base angles 6a and 6b are rotatably fixed to the seat plate 3 by respective stepped bolts 7 through the two base angles 6a and 6b. Each base angle 6a, 6b has a backing 10a on the mirror frame 9a, 9b for each half 8a, 8b of the reflector 8.

10b and a holding fitting 11a surrounding it.

111) are fixed by bolts and nuts 12a, 12b, and supporting frames 13a, 15b, i4a, 14b are fixed. Support frame 13a.

13b, 14a, 14b are the respective halves 8a, 8 of the reflecting mirror 8.
Circumferential support frames 15a, 15b and diameter support frame 14 of No.b
a, 14b. The holding fittings 11a, 11b are attached to each of the circumferential support frames 13a, 13b and the diameter support frames j4a, 14b at a plurality of locations, respectively, and hold each of the reflecting mirror halves 8a, 8b to the housing 1 via the lens frames 9a, 9b. I will support it.

On each base angle 6a, 6b, another stepped bolt 15°15 is installed at a constant distance from the stepped screw 7, and each stepped bolt 15 has a washer 17 and a nut 16.
The link 18 is rotatably attached to the stepped bolt 15.

The other end of the link 18 is similarly attached to another stepped bolt 19 and washer 2.
0. It is fixed to a common link plate 22 by a nut 21.

The link plate 22 is guided so as to be movable in a direction parallel to the optical axis of the reflecting mirror 8 in a guide 23 having a cross-sectional opening shape, and the guide 25 is fixed to the inner surface of the housing 1. A driven pin 24 is installed on the link plate 22, and the driven pin 24 is fitted into a groove 26 of a grooved cam 25 formed as an eccentric cam, and the driven pin 24 is removed by a screw 27 at the upper end. A stop plate 28 is fixed.

The grooved cam 25 is fixed to a camshaft 29. This fixation is achieved by engaging the square shaft head 29a of the camshaft 29 with the grooved cam 25 of the square hole 25a, and fixing it with a washer 50 and a screw 31.

The camshaft 29 is inserted into the inside of the housing 1 from the outside of the housing 1 and has a flange 34 welded to the housing 1.
It is supported by a bearing 33.

The camshaft 29 includes a seal groove 29c, and a seal ring 32 is fitted into the seal groove 29c.

Two receiving holes 35 for balls 41 are formed in the flange 34 of the +111 bearing 55 at a constant radius from the central axis of the bearing 33. The central angle between the accommodation holes 35 is the reflecting mirror half 8a.
, 8b corresponds to the rotation angle of the grooved cam 25 for adjusting the rotation angle. A lever 38 is fixed to the other end of the camshaft 29 by a washer 36 and a screw 37, and a guide 39 is welded to the lever 38 at a location corresponding to the hole 35.
A ball 41 and a compression spring 42 are pushed into the hole 40, and are pressed by a set screw 43 and a nut 44 to release the ball 4.
1 is elastically engaged in the accommodation hole 35. A needle 45 (at the end of 38) is fixed with a rivet or the like.

The operating device according to the invention operates as follows.

From the position shown in FIG. 1, the handle 45 is rotated approximately 60 degrees clockwise as viewed in FIG. 1 by operating the handle 45 until the ball 41 engages in the other receiving hole 35.

At this time, the driven pin 24 and therefore the link plate 22 are moved by the eccentric cam 25 several inches to the right as viewed in FIG. As a result, both base angles 6a, 6b rotate around the stepped screw 7 via the link 18. The base angle 6a rotates counterclockwise, and the base angle 6b rotates clockwise. Support frames 13a and 14 attached to left and right reflecting mirror halves 8a and 8b are attached to both base angles 6a and 6b.
Since a, 13b, and 14b are fixed, both halves 8a
, 8b indicates that light emitted from a light source (not shown) at the focal point of the reflecting mirror 8 is reflected from both halves 8a and 8b in FIG. deflected to cross each other.

As a result, the optical axis direction of the light reflected by each of the reflecting mirror halves 8a, 8bK can be changed, and the direction of the searchlight projection can be changed.

By increasing the number of ball catch devices 35 and 41 shown in FIG. 2, it becomes possible to set the reflector even at an intermediate position of the rotation of the handle 450.

According to the operating device according to the present invention, the rotational adjustment of the reflecting mirror can be carried out easily and accurately with a simple and rational structure.

The actuating device according to the invention is extremely advantageous for simultaneous and accurate adjustment of the pivoting angle of objects other than reflectors, in particular of a plurality of elements and for holding the elements in the adjusted position.
