Description

Camera Mount {FIXING DEVICE FOR CAMERA}

The present invention relates to a camera mount, and more particularly, to a camera mount that stably supports a camera while absorbing vibration.

In general, an installation device for installing a camera includes a tripod called a tripod, a crane equipped with a boom on which the camera is mounted, or a cradle installed in the form of a cantilever on an artificial structure (eg, a wall, ceiling, column, etc.).

Here, in the case of the above-mentioned cradle, it consists of a boom installed on the wall in a horizontal state, and a camera sheet for mounting the camera is installed at the end of the boom. And, the boom is usually composed of a single rod, and hinges are mounted on both ends so that both ends are rotated around the hinge when necessary. That is, the boom can be rotated around the hinge when necessary to form an inclination or to achieve a level. At this time, rotation of the boom is controlled manually by loosening and re-tightening the screw fastened to the hinge, or when a motor is installed in the hinge, the rotation is automatically controlled by driving the motor.

However, such a conventional cradle has the inconvenience of having to operate the screws installed at both ends of the boom, respectively, and there is a problem in that it cannot be used in case of a motor failure. And, since the boom is composed of a single rod, when external vibration is transmitted to the artificial structure, the vibration is amplified by the length of the rod, causing the camera to shake severely.

In order to solve this problem, the applicant of the present invention has applied for a patent for a "camera cradle" that can solve the above problems with the Korean Intellectual Property Office and has been registered (Registration No. 10-1832935) on February 21, 2018. This prior art provides an upper arm and a lower arm that are respectively rotatably fixed at both ends to a fitting bracket fixed to a wall and a camera hanger on which the camera is mounted, and a rotational force required for tilting the upper arm and the lower arm by providing the upper arm and the lower arm. It is composed of a tilting adjuster that adjusts the tilting angle, and the angle of the upper arm or lower arm can be easily adjusted through the tilting adjuster. As it is configured so that it does not easily flow during the operation, the vibration of the artificial structure transferred to the upper arm and the lower arm can be suppressed as much as possible.

On the other hand, the applicant of the present invention immediately started again to develop an improved technology capable of further mitigating the vibration transferred from an artificial structure such as a wall after filing the above-mentioned prior art, and as this improved technology is completed, the present invention was filed for

In particular, as a finishing plate is installed on the surface of an artificial structure such as a wall or a column, and a space is formed between the artificial structure and the finishing plate, an improved technology that can dampen vibration even if the length of the anchor bolt fixing the fitting bracket becomes longer has been completed. Accordingly, the present invention was applied for.
