Lid opening and closing device

Abstract

A lid opening and closing device includes a first lock mechanism 5 for retaining a fully-closed position of lids 3a, 3b, a torsion coil spring 6 for accumulating an urging force in a direction so as to open the lids, and a release button 4 for unlocking the first lock mechanism. When the release button is pressed, the lids automatically open. The lid opening and closing device further includes a compression coil spring 9 for accumulating an urging force which allows the lids to move to a halfway position in a closing direction from a fully-open position, and a second lock mechanism 11 for retaining the compression coil spring in a compression position. When the release button is pressed at the fully-open position of the lids, the second lock mechanism is unlocked and the lids move to the halfway position in the closing direction. The urging force is accumulated in the torsion coil spring and the compression coil spring by manually moving the lids to the fully-closed position.

Description

FIELD OF THE INVENTION[0001]This invention relates to a lid opening and closing device, especially, the lid opening and closing device suitable for a type of accessory box whose lids are stored in a storage portion when the lids are fully open.BACKGROUND OF THE ART[0002]For example, for an accessory box provided in a center console of an automobile and the like, one with a lid with a lateral opening whose one end is interconnected with an open surface of a goods storage portion by using a hinge, is well-known. If this lid projects when the lid is open, it becomes an obstacle. Thus, the lid is preferably constituted so as to be stored on the outside of a side wall of the goods storage portion. If the lid is constituted so as to be completely stored, the appearance becomes good. On the other hand, a loose end of the lid can be easily submerged from the open surface. As a result, the closing operation is interfered. Accordingly, one using a reversal spring in which urging forces to bot...

AI Technical Summary

Benefits of technology

The present invention is a lid opening and closing device for an accessory box, especially for an automobile. The device uses a reversal spring to automatically perform opening and closing movements of the lid. However, this conventional device has limitations in securing sufficient retaining force in both fully-open and fully-closed positions, and also has a high operating force and quantity. The invention aims to solve these issues by providing a lid opening and closing device that securely retains the lids in both positions and reduces the operating force and quantity required for unlocking. The device includes a lock mechanism, an urging-force accumulation member, and an operating portion. The lids are automatically opened when the operating portion is unlocked, and the device includes covers that move with the movement of the lids. The invention also includes a shared operating portion that can perform both the opening and closing operations, simplifying the structure of the device.

Problems solved by technology

If this lid projects when the lid is open, it becomes an obstacle.

As a result, the closing operation is interfered.
