Description

この発明は、固定部材に対して開閉体を開閉自在に連結し、任意の回転角度で保持するヒンジ機構およびそれを備えたモニタ装置に関するものである。 The present invention relates to a hinge mechanism that connects an opening / closing body to a fixed member so as to be freely opened and closed, and holds the rotation member at an arbitrary rotation angle, and a monitor device including the hinge mechanism.

この発明は、上記のような課題を解決するためになされたもので、ガタを抑制して、衝突音の発生を防止したヒンジ機構およびそれを備えたモニタ装置を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a hinge mechanism that suppresses backlash and prevents the occurrence of collision noise, and a monitor device including the hinge mechanism.

この発明によれば、折り曲げ部をシャフト部にカシメ固着するようにしたので、当該折り曲げ部と同一部材のクリック用ばね部がシャフト部と同期してガタ無く回転できる。また、カシメ固着部分を間に挟んで向かい合わせにクリック用ばね部のクリック用凹凸部の一方と折り曲げ部の摩擦用凸部とを設けるようにしたので、ベース部とクリック用ばね部のクリック用凹凸部が係合した状態で開閉体に振動が加わった場合でもクリック用凹凸部の係合による保持力と摩擦用凸部の摩擦抵抗とによって板ばね部が動きにくくなるため、ベース部のシャフト部を軸支する回転軸穴とシャフト部とに軸ガタが生じていても衝突しにくくなる。従って、ガタを抑制して、衝突音の発生を防止したヒンジ機構およびそれを備えたモニタ装置を提供することができる。 According to this invention, since the bent portion is caulked and fixed to the shaft portion, the click spring portion of the same member as the bent portion can rotate without play in synchronization with the shaft portion. In addition, one of the click uneven parts of the click spring part and the friction convex part of the bent part are provided facing each other with the caulking fixed part in between, so that the click part for the base part and the click spring part is clicked. Even when vibration is applied to the opening and closing body with the concavo-convex part engaged, the leaf spring part becomes difficult to move due to the holding force due to the engagement of the click concavo-convex part and the frictional resistance of the friction convex part. Even if there is axial backlash between the shaft hole and the rotating shaft hole that pivotally supports the part, it becomes difficult to collide. Therefore, it is possible to provide a hinge mechanism that suppresses backlash and prevents the occurrence of collision noise, and a monitor device including the hinge mechanism.
