Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera support device, and particularly to a support device suitable for supporting a camera having a heavy lens.

[Prior art]

FIG. 1 shows a conventional camera support device. In the figure, 1 is a camera support tripod that supports a camera unit 3 of the camera on a board 2. However, with this type of support device, problems arise when the weight of the lens portion 4 becomes heavy. That is, since the lens section 4 and camera section 3 are connected by the mount 5,
This mount part could not withstand the weight and would break, or it would be elastically deformed and the optical axes would no longer align.

[Configuration to solve the problem]

The present invention has been made in view of this point, and therefore, an object of the present invention is to provide a camera support that protects the mount. This objective is achieved by supporting the camera section and the lens section with separate supports. however,
Since the lens section and camera section differ depending on the type of interchangeable lens, etc., the support device of the present invention is configured so that the height of at least one support tool can be adjusted with respect to the other. A support device that supports a camera body and a photographic lens that can be attached to a mount of the camera body, comprising support substrates 2 and 6 for supporting the photographic lens, and first and second substrates that support the camera body. 2 support plates 16, 17,
A spring member 15 for supporting the support plates 16 and 17 against the support substrate 2, a lever 18 for fixing the second support plate 17 to the first support plate 16, and a lever 18 for fixing the second support plate 17 to the support substrate 2. A fixing means 14 for fixing the second support plate 17 is provided.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings. This embodiment is an example in which the camera part support of a handy TV camera is adjustable and the lens part is fixed.

In FIG. 2, a lens 4 is fixed to a substrate 2 via a lens support 6, and a camera body 3 is fixed to a camera support plate 7 via screws or the like. This camera support plate 7 is located at the third section taken along the line A-A in FIG.
As shown in the figure, it has a flange 8 on the lower surface.
This flange 8 is provided with a long hole 9 and is held between flanges 10 and 11 of the substrate 2. A screw handle 14 passes through the elongated hole 9 through the screw holes 12 and 13 of the flanges 10 and 11. Therefore, the vertical position of the camera support plate 7 can be adjusted by loosening the screw handle 14, and the position can be fixed by tightening the screw handle 14. 15 is a spring provided between the support plate 7 and the substrate 2. This spring 15 protects the mount 5 by receiving the weight of the camera section 3 when the support plate 7 is movable up and down. These members allow the vertical position to be adjusted.

Next, a mechanism for adjusting the camera in the left-right or front-back direction will be explained.

As shown in FIG. 2, the substrate 7 includes an upper plate 16 and a lower plate 1.
It consists of two boards of 7. 18 is this upper plate 16
This is a cam lever that allows the and lower plate 17 to be integrated or separate. The mechanism of this part is shown in FIG. 4, which is a cross section taken along line BB in FIG. 2. The cam lever 18 is rotatable with respect to the upper plate 16. An eccentric cam 19 is fixed to this lever 18. 20 is a leaf spring provided on the lower plate 17. Eccentric cam 19 on this leaf spring
are in contact. Therefore, when the cam lever is rotated to bring the cam 19 into strong contact with the spring 20, the upper plate 16 and the lower plate 17 become one body, and when they are brought into weak or non-contact, they become separate bodies. Therefore, by bringing the cam 19 and the spring 20 into a non-contact state, they become separate bodies, and the upper plate 16 can be adjusted left and right with respect to the lower plate 17 within the range limited by the gap 21, and also can be adjusted in the front-rear direction (not shown). It is adjustable in the front-back direction while being limited by the clearance.

The adjustment method will be explained below.

(i) Place the camera 3 on the camera support plate 7 with the screw handle 14 loosened, and then fix the lens 4 with the mount. At this time, since the weight of the camera is supported by the action of the spring 15, there is almost no load on the mount section.

(ii) Rotate the handle 14. Thereby, the camera support plate 7 and the substrate 2 are fixed.

(iii) Rotate the lever 18. As a result, the upper plate 16 and the lower plate 17 are separated and can be adjusted horizontally and forward and backward, and then these are fixed, and the camera is fixed to the substrate 7.

Note that (ii) and (iii) may be reversed.

Furthermore, when the camera is mounted, if the height of the camera is set to approximately match the height of the lens mount and the strength of the spring 15 is set to balance the weight of the camera, almost no force is applied to the mount 5.

Note that it is also possible to fix the camera to the substrate and place the lens on the vertically adjustable support 7.
