Cover opening-and-closing support mechanism employing gas spring, and automatic transaction apparatus

摘要

A cover opening-and-closing support mechanism is provided that reliably locks a gas spring, and in which a rod section of a gas spring is not damaged by a stopper portion. The cover opening-and-closing support mechanism includes: a gas spring equipped with pivot points at both end portions and including a cylinder section and a rod section; a stopper portion rotatably provided at the pivot point at a first of the end portions, the stopper portion making contact with the cylinder section when the gas spring has been extended so as to lock the gas spring; a gas spring stopper including a limiter portion that makes contact with the cylinder section before the stopper portion makes contact with the rod section; and a release handle portion for releasing the locking, provided at the gas spring stopper on substantially an opposite side to the stopper portion, such that the gas spring stopper swings towards substantially the opposite side to the stopper portion due to a weight of the release handle portion.

主权项

1. A cover opening-and-closing support mechanism comprising:
a gas spring having a first pivot point at a first end portion and a second pivot point at a second end portion, the gas spring including a cylinder section and a rod section; a gas spring stopper including a limiter portion that contacts one side of the cylinder section, and including a stopper portion that contacts a top side of the cylinder section; and a release handle portion that unlocks the gas spring, the release handle portion disposed at the gas spring stopper on substantially an opposite side of the stopper portion, such that the gas spring stopper swings towards substantially the opposite side of the stopper portion based on a weight of the release handle portion; wherein the limiter portion is disposed at a predetermined distance away from the stopper portion in a direction away from the cylinder section; wherein the stopper portion and the limiter portion are disposed at the gas spring stopper at an opposite side of the release handle portion; and wherein the stopper portion locks the gas spring when the gas spring has been extended and the stopper portion contacts a bottom side of the cylinder section, and the limiter portion limits movement of the stopper portion by contacting a side surface of the cylinder section such that the stopper portion does not contact the rod section of the gas spring when the gas spring is locked.
