Device supporting arm

Abstract

A device supporting arm is composed of a plurality of arms, an adjacent arm is equipped with a fixing side positioning guiding member arranged on a bearing thereof, another arm is equipped with a movable side positioning guiding member, possesses a rod of a pushing and pressing part and a locking part. After adjacent arms are adjusted at any rotation angle, by rotating an operating rod towards a specified direction, the movable side positioning guiding member is pushed and pressed towards the fixing side positioning guiding member via the pushing and pressing part, so that the pushing and pressing part is clamped with the locking part to lock the rotation angles between arms. By rotating the operation rod towards a reverse direction, the locking is relieved. By the structure, various devices, such as monitor, etc., can be kept at the specified position required by users in the long term and stably.

Description

technical field [0001] The present invention relates to a device supporting arm for supporting monitors, computers, televisions and other various devices so as to be freely movable in left and right directions or in up and down directions. Background technique [0002] Conventionally, various devices such as monitors, computers, and televisions have been installed in offices, homes, etc., or in vehicles such as automobiles, airplanes, ships, etc., with various types of device support arms. In general, a plurality of arms of the device supporting arm are rotatably connected to each other by a hinge device, and each arm is connected so as to maintain any rotation angle, and the base end side arm is fixed at the installation end, and the front end side arm is installed. Various means are provided on the mounting end so that the various means are freely movable within the length of each arm. For example, Japanese Patent JP-9-326980-A discloses such a device support arm. In the...

Problems solved by technology

[0003] However, in the above-mentioned conventional device support arms, each joint member between a plurality of arms is constituted by a hinge mechanism that provides frictional resistance between the arms only by using butterfly springs or washers, since only the butterfly The frictional resistance action of springs or washers, etc. bears the load of various devices such as monitors and the load of various arms, so the load is too large for the ability of this joint part to maintain the angle between the arms

Therefore, the problem with this support arm is that the ability to support various devices such as monitors gradually decreases shortly after use, and the device gradually falls, so that it cannot be stably maintained at the specified position required by the user for a long time.

In addition, when such a device supporting arm is used in a vehicle, for example, it is easily affected by vibrations, so the supported device tends to fall, making it difficult to maintain the most suitable position for the user stably for a long time.
