Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing cover mounting structure for a cover device in which one end of a thick opening / closing cover can be closed by approaching a front end surface of a fixed frame portion.

[0002]

2. Description of the Related Art Conventionally, a fulcrum in which the other end of a thick opening / closing cover capable of fitting one end portion close to the front end surface of a fixed frame portion is offset outward from the outer surface of the frame portion. In a cover device configured to be pivotable on a shaft, the other end of the opening / closing cover can be opened and closed by rotating about the fulcrum shaft as it is.

[0003]

However, if the thick opening / closing cover is rotated about the fulcrum shaft as it is,
Since the end surface of the opening / closing cover rotates in an upward trajectory, the end surface of the opening / closing cover must be set so that the end surface of the opening / closing cover does not contact the end surface of the frame portion. When the cover is closed, there is a problem that a large gap is left between the front end surface of the frame portion and the one end side end surface of the opening / closing cover.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised so as to solve such a problem and to make it simple and suitable for implementation. Therefore, the inside of the other end of the opening / closing cover is provided inside. A long groove in the cover longitudinal direction to be fitted to the fulcrum shaft is provided, and the inside of the cover near the one end thereof is provided with an opening / closing cover when fitted to a locking shaft extending inward from the outer surface of the frame portion. An engaging body having an engaging guide groove which can be moved so as to approach the front end face side of the frame portion is fixedly provided.

[0005]

Accordingly, when the cover is rotated around the fulcrum shaft dropped into the long groove when the cover is closed, the engagement guide groove of the engaging body is fitted to the locking shaft. When the engagement guide groove slides into the locking shaft,
The opening / closing cover is moved so as to approach the frame side while the long groove also slides on the fulcrum shaft. When the locking shaft is fitted into the inner end side of the engagement guide groove, the tip of one end of the opening / closing cover is formed. The surface is closed close to the front end surface of the frame so that the gap is small, and when the open / close cover is opened, the operation is performed in the reverse of the above operation, and one end of the open / close cover is opened. The opening / closing cover moves so that the front end surface of the portion is separated from the front end surface of the frame portion, and can be safely opened by falling into the long groove on the fulcrum shaft.
