Description

Multipurpose cradle

The present invention relates to a multi-purpose cradle, and more particularly, to a multi-purpose cradle that stably supports an object to be mounted while absorbing vibrations.

Recently, the development of a cradle for installing a mounting object, a sensor, a display device, etc. inside and outside a building, a moving means such as a vehicle, etc.

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

In addition, it is common that sensors, etc. are mounted and installed integrally on the inner and outer walls of a building.

Here, in the case of a cradle capable of accommodating the above-described cradle object, it is composed of a boom installed in a horizontal state on the wall, and a cradle object sheet for mounting the cradle object is installed at an 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, thereby causing a problem in which the object to be mounted is severely shaken.

In addition, when the sensor is mounted in a fixed manner, external vibration may be transmitted to the sensor and the like, which may cause a malfunction of the sensor.

The need for a multi-purpose cradle that can be stably mounted without transmitting vibration to a vibration-sensitive object, such as a mounting object, a sensor, a display, etc., is increasing.
