Lid opening and closing device and storage apparatus

摘要

A lid opening and closing device includes a first supporting shaft, a guide surface, a second supporting shaft, an opening and closing key supported by the second supporting shaft, an arm member and a lever member, wherein when an insert is not present in a box, a lid is suspended from the first supporting shaft and covers the box and enters a closed state, and when the insert is inserted into the box through an opening, the insert causes the opening and closing key to swing in an insertion direction, an end of an arm member rises along the guide surface in synchronization with the swinging of the opening and closing key, the risen arm member lifts an end of the lever member, and the lid, to which the lever member is secured, swings around the first supporting shaft and enters an open state.

主权项

1. A lid opening and closing device that opens and closes a lid that covers a box having an opening through which an insert is inserted, the device comprising:
a first supporting shaft that extends horizontally and perpendicular to an insertion direction in which the insert is inserted, the first supporting shaft pivotally supporting one end of the lid, the lid being swingably suspended from the first supporting shaft; a guide surface, extending along the insertion direction, a height of which is gradually increased from the opening in the insertion direction; a second supporting shaft parallel to the first supporting shaft, the second supporting shaft being disposed nearer to the opening than the lid in the insertion direction; an opening and closing key being pivotally supported by the second supporting shaft and being swingably suspended from the second supporting shaft; an arm member, a first end of which is secured to the opening and closing key and a second end of which moves on the guide surface in synchronization with swinging of the opening and closing key; and a lever member, secured to the lid, that swings around the first supporting shaft together with the lid, one end of the lever member being disposed on an upper surface of the arm member, wherein when the insert is not present in the box, the lid is suspended from the first supporting shaft and covers the box and enters a closed state, and when the insert is inserted into the box through the opening, the insert causes the opening and closing key to swing in the insertion direction, the second end of the arm member rises along the guide surface in synchronization with the swinging of the opening and closing key, the risen arm member lifts the one end of the lever member, and the lid, to which the lever member is secured, swings around the first supporting shaft and enters an open state.
