Abstract

In an opening-closing mechanism of a door member for shifting the door member from a closed position for closing an opening portion of a base member to an open position and vice versa, the door member includes a pair of arm portions. Each arm portion includes a circular arc shape gear and a rotary gear disposed in a center of the circular arc of the gear. The base member includes a first fixed gear portion with internal teeth engaging the circular arc shape gear portion, and a second fixed gear portion disposed inside the first fixed gear engaging the rotary gear. The arm portion is held to move vertically through engagements between the first fixed gear portion and the circular arc shape gear portion and between the rotary gear and the second fixed gear portion, so that the door member is shifted along a path corresponding to the first fixed gear portion.

Description

technical field [0001] The present invention relates to an opening and closing mechanism for opening and closing a door body to a box-shaped base, and an opening and closing device using the same. In addition, the "box-shaped base" in this specification includes various storage bodies, boxes, etc., and the "door" is an object in a broad sense including lids, coverings, and the like. Background technique [0002] Figure 8 with Figure 9 In the opening and closing mechanism of a door, two conventional examples of the form which switch a door are shown. Figure 8 The opening and closing mechanism of (a) is, for example, a structure similar to that disclosed in Japanese Patent Application Laid-Open No. 9-20177, and the door 42 opens and closes the opening of the box-shaped base 41 by 90 degrees of rotation. That is, a braking damper mechanism 43 having a rotary rotation gear 43 a is attached to the side wall portion of the base body 41 . The door body 42 has an arm 44 protrud...
