On the device.

Further, the vibration isolation means may be composed of a vibration-proof rubber that comes into contact with the camera base and a spring that biases the vibration-proof rubber toward the camera base.

<Operation> A camera stand for fixing the camera and a lift stand for raising and lowering the camera stand are formed as separate bodies, and the vibration isolation means is interposed between the camera stand and the lift stand. . Therefore, even when the vibration generated by the elevating means is transmitted to the lift base, this vibration is absorbed by the vibration isolating means interposed between the lift base and the camera base, and the vibration is supported by the camera base. Prevents transmission of vibration.

<Embodiment> A photographing lift device according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a photographing lift device. Shooting lift device 10
Is formed by vertically supporting the column 12 vertically fixed on the lift base 11, slidably mounted along the column 12, and penetrating the camera platform 17 described later slightly along the column. Lift base 13 and winch 14 for lifting the lift base 13
And a camera base 17 for fixing the video camera 15 installed on the platform 16 constitutes a main part.

The support columns 12 are provided on a pair of side surfaces facing each other at right angles to the mounting side surface of the video camera 15, and the guide rollers 13a of the lift table 13 are provided.
Fitting grooves 18 that fit with are provided in the vertical direction,
Lift tables 13 respectively arranged on the pair of opposed side surfaces.
The guide roller 13a is fitted into the fitting groove 18 and is slidable along the column 12.

The camera stand 17 is a column 12 having a lift stand 13 on both sides thereof.
A slide support portion 17a that is telescopically fitted into the outer peripheral portion of the camera and a camera support portion 17b that mounts the video camera 15 are integrally formed, and the pillar 12 is provided inside the slide support portion 17a. The guide rollers 19 _{1 to} 19 ₄ that come into contact with the mounting-side side surface of the video camera 15 and the opposite side surface thereof, respectively.
It is provided at the upper end and the lower end of 17a.

As shown in FIG. 2 and FIG. 3 in an enlarged manner, the lift base 13 is formed to be longer than the camera base 17, and the lower end of the lift base 13 exposed from below the camera base 17 is exposed. Is equipped with a vibration isolation device 20. The vibration isolation device 20 is the camera stand.
It is composed of a vibration-proof rubber 20a that abuts against 17, a spring 20b that biases the vibration-proof rubber 20a upward, and a storage case 20c fixed to the lift table 13 that stores the spring 20b.
Therefore, the camera base 17 has its lower end portions on both sides mounted on the vibration-proof rubber 20a biased by the spring 20b, and is supported in a cushioned state.

Further, as an elevating device for the lift table 13, one end of a wire rope 21 is fixed to an upper end portion of the sliding support portion 17a on the mounting side of the camera 15, and a pulley 22 provided at an uppermost portion of the column 12 is interposed. The other end is connected to one end of a chain 23, and the chain 23 has a mechanism in which the other end is wound by the winch 14 via a chain wheel 24. Therefore,
By lifting and unwinding the chain 24 with the winch 14, the lift table 13 can be raised and lowered, whereby the lower end portion is supported by the vibration isolation device 20 attached to the lift table 13. In addition, the camera stand 17 moves up and down with respect to the column 12.

When the video camera 15 is actually moved up and down with respect to the column 12, vibrations occur in the rotation unevenness of the winch 14 and the chain 23, the wire rope 21, etc., and this vibration is transmitted to the video camera 15 and It will cause blurring. However, when this vibration is transmitted to the lift base 13, it is interposed between the lift base 13 and the camera base 15,
The vibration is absorbed by the spring 20b and the vibration-proof rubber 20a that are contracted under the load of 15, and the vibration of the lift base 13 can be prevented from being transmitted to the camera base 17.

In the present embodiment, the mechanism constituted by the vibration isolating rubber and the spring is illustrated as the vibration isolation device, but the invention is not limited to this, and absorbs the vibration of the lift table 13 by using hydraulic pressure or air pressure, There is no problem if the mechanism does not transmit vibration to the camera stand 17 side.

<Effect> According to the photographing lift device according to the present invention, a lift base slidably attached to a column and provided with a vibration isolation means, and a camera base for supporting and fixing a photographing device such as a video camera. Since each of them is formed as a separate body, and the configuration in which the camera base is mounted and fixed on the vibration isolation means is adopted, the vibration generated from the lifting means at the time of lifting and transmitted to the lift base is transferred to the lift base and the camera base. There is an excellent effect that it can be absorbed by the vibration isolating means interposed between the two, and this vibration is prevented from being transmitted to the camera base, and that a captured image without blurring can be provided even when the lift base is moved up and down.
