Description

[Detailed description of the invention] This invention relates to a lid opening/closing structure consisting of a box with an open front and a lid that slides to open and close the opening of the box. The sliding direction is vertical, and the closed state that the lid moves upward can be fixed by magnetic force, and when the lid is released from this magnetic force, it descends under its own weight to obtain the open state. Theory of closing the lid,
The purpose of the present invention is to provide a lid opening/closing structure that is extremely easy to open and close by releasing it from the magnetic force, can be opened and closed with a simple one-touch operation, and has a simple structure.

To explain the example shown below, 1 is a box body, 2 is a box body 1
A sliding guide groove 5 for the lid 4 is formed between the front frame and the rising piece 3a of the L-shaped member 3 provided on the inner surfaces of the side plates 1a and 1a.

Note that the sliding guide groove 5 or, for example, a guide groove member having a U-shaped cross section may be simply attached to the inner surfaces of the side plates 1a and la of the box body 1, and the front frame 2 and the L-shaped member 3 are not necessarily required. do not.

The lid 4 is vertically movable through an entrance/exit 1C formed in the bottom plate 1b of the box 1, and its upper edge is bent inward to form a bent piece 4a.

This bent piece 4a serves both as a pull-out stop and as an attraction surface for the magnet.

That is, in this invention, the magnet 6 is used as a locking tool for the lid 4, and when the lid 4 is moved upward and closed, 1. The bent piece 4a is attracted and fixed by the magnet.

This is how it was done. In the drawing, one magnet 6 is provided on both the left and right sides of the top plate 1d near the opening surface of the box 1, but one stopper is provided at approximately the center position, and the magnet 6 is provided on the right side in FIG. A push button 7, which will be described later, may be placed at the stop position.

Furthermore, the new bending pieces 4a do not necessarily have to be a series of pieces as shown in the drawings, and a structure in which bent pieces are formed only at corresponding positions of the magnet 6 may be adopted.

The push button 7 is held on the top plate 1d so as to be able to move downward -L by penetrating the top plate 1d. - The bent piece 4a of the lid body 4;
Alternatively, if there is no bent piece, the lower end thereof is in contact with the upper edge, and when the lid body 4 is closed, the head 7a is slightly protruded from the upper surface of the top plate 1d.

Therefore, to open the lid, press this push button 7 to push down the lid 4 slightly, pull the lid away from the magnet 6, and release the fixed state due to the magnetic force.This causes the lid 4 to fall under its own weight. However, the lid is opened.

Reference numeral 8 denotes an elastic material for alleviating the collision sound between the box bottom plate 1b and the bent piece 4a when the lid 4 is lowered, and also serves to prevent the lid 4 from falling when pulled out.

Regarding the mounting position of the push button 7 and the magnet 6, in terms of the way the force is applied to separate it from the magnet, it is better to move the push button 7 to one side as described above than in the mounting state shown in the figure. It can be said that it is preferable to place the magnet near the center of the magnet because it is easier to separate the magnets.

As mentioned above, the opening/closing structure of the lid body according to this invention is only released from the fixing force caused by magnetic force by one-touch operation of the push button provided on the top plate of the box body, and the lid body as a vertically movable member is moved by its own weight. The lid descends, and the presence of the bending piece prevents it from falling, opening the lid.When closing, the lid can be simply pushed up and returned to its original position, and no springs are used. Its opening and closing operations are extremely easy.

Furthermore, an elastic material is provided on the bottom plate of the box body as an auxiliary member to prevent the lid from being pulled out, and this reduces the collision noise between the bent piece and the bottom plate when the lid is opened due to its own weight falling.

In addition, the closed state of the lid is fixed by magnetic force, and the opening operation uses the drop of its own weight due to the release of the magnetic force, and as mentioned above, no spring force is used, so the overall structure can be summarized very simply. It also has the advantage of being obtained.
