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 stand and the support frame of the reflector. The support frame of the reflector is pivotally supported to the base of the searchlight body by upper and lower support shafts, and the bolt attached to the base of the light body controls the support frame of the reflector to rotate around the support shaft. It was screwed into a slide piece fitted into a groove, and was tightened or loosened by tightening or loosening the bolt. However, in such a structure, since the distance from the spindle to the support frame is relatively large, 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 becoming more complex.

In view of the above, it is an object of the present invention to create an operating device that has a simple structure and 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, particularly 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, multiple members can be accurately rotated and adjusted at the same time with a single touch. It is characterized in that it is made to be

Embodiments of the present invention will be described based on the drawings.

1 to 4, a substrate 2 is fixed on the housing 1 and to the inner surface of the housing 1, and a seat plate 3 is fixed on the substrate 2. As shown in FIGS. Two base angles 6a and 6b are rotatably fixed to the seat plate 3 by means of spring washers 4 and flat washers 5, respectively, on stepped bolts 7. Each base angle 6a,
6b, packings 10a, 10b and holding fittings 11a, 11b surrounding them are fixed to mirror frames 9a, 9b for each half 8a, 8b of the reflecting mirror 8 by bolts and nuts 12a, 12b. Support frames 13a, 13b, 14a, and 14b are fixed. Support frames 13a, 13b, 14a, 1
4b are circumferential support frames 13a, 13b and diameter support frames 14a, 1 for each half 8a, 8b of the reflector 8.
4b. The holding fittings 11a, 11b are attached to each circumferential support frame 13a, 13b and the diameter support frame 14a, 1
The reflecting mirror halves 8a and 8b are respectively attached to the housing 1 at a plurality of locations through the lens frames 9a and 9b.

A stepped screw 7 is provided on each base angle 6a, 6b.
Another stepped bolt 15, 15 at a certain interval from
A link 18 is rotatably attached to the shoulder bolt 15 by a washer 17 and a nut 16, respectively.

The other end of the link 18 is similarly connected to another stepped bolt 1.
9, is fixed to a common link plate 22 by a washer 20 and a nut 21.

The link plate 22 is a guide 23 having a cross-sectional shape.
The guide 23 is guided movably in the direction parallel to the optical axis of the reflecting mirror 8.
is fixed to the inner surface of the A driven pin 24 is installed on the link plate 22.
4 is a groove 2 of a grooved cam 25 formed as an eccentric cam.
6, and the driven pin 24 has a screw 2 at its upper end.
7, the retaining plate 28 is fixed. The grooved cam 25 is fixed to a camshaft 29. This fixation is done by using a square hole 25 in the square shaft neck 29a of the camshaft 29.
The grooved cam 25 of a is engaged and fixed by a washer 30 and a screw 31. The camshaft 29 is inserted from the outside of the housing 1 into the inside of the housing 1 and is attached to a bearing 33 of a flange 34 that is welded to the housing 1.
is supported by.

The camshaft 29 includes a seal groove 29c, and a seal ring 32 is fitted into the seal groove 29c. The ball 41 is accommodated in the flange 34 of the bearing 33.
5 are formed at two locations on a constant radius from the central axis of the bearing 33. The central angle between the accommodation holes 35 corresponds to the rotation angle of the grooved cam 25 for adjusting the rotation angle of the reflecting mirror halves 8a, 8b. 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 in and pressed by a set screw 43 and a nut 44, so that the ball 41 is elastically engaged in the accommodation hole 35. A handle 45 is fixed to the end of the lever 38 by rivets or the like.

The operating device according to the invention operates as follows.

The handle 45 is operated from the position shown in FIG. 1, and the handle 45 is rotated approximately 60° clockwise as viewed in FIG. 1 until the ball 41 engages with the other receiving hole 35.

At this time, the driven pin 24 and the limp plate 22 are moved several mm to the right by the eccentric cam 25 as seen in FIG.
Moving. 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.
a, 13b, and 14b are fixed, so that both halves 8a and 8b receive light emitted from a light source (not shown) at the focal point of the reflecting mirror 8.
The reflections from a and 8b, which are parallel to each other, are deflected to cross each other by operating the handle.

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

By increasing the number of ball catch devices 35, 41 shown in FIG. 2, it becomes possible to set the reflector even at an intermediate position of rotation of the handle 45.

According to the operating device according to the present invention, the rotational adjustment of the reflector can be easily and accurately carried out 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.
