By the way, the opening / closing operation of the lid body is realized by switching between the engagement between the rod and the box body and the disengagement by moving the rod in the opening / closing mechanism. That is, in each opening / closing mechanism, the rod can be switched between engagement and non-engagement with the engagement hole of the box body by advancing and retreating while being supported by the lid body. In this structure, in order to smoothly and reliably advance and retreat the rod in the opening / closing mechanism, it is effective to provide a clearance at a sliding portion where the rod and the lid can come into contact with each other. However, if the opening / closing mechanism is provided with a clearance, contact between the rod and the main body of the lid may occur when the rod moves forward and backward, and abnormal noise or operation noise may be generated.

In order to prevent the generation of abnormal noise and operation noise due to the above clearance, the rod is adjacent to the rod in an orthogonal direction orthogonal to the advancing / retreating direction so that the rod and the lid do not come into contact with each other. It is conceivable to provide a cushioning material. According to this cushion material, the movement of the rod can be regulated by interfering with the moving rod when it moves in the above-mentioned orthogonal direction. Therefore, it is possible to prevent the rod from coming into contact with the lid when moving back and forth, and to prevent the generation of abnormal noise and operation noise due to the above clearance, that is, to prevent rattling. However, in the structure in which the cushion material is provided adjacent to the rod as described above, the rod may slide in contact with the cushion material and frictional resistance may be generated when the rod advances and retreats, so that the rod advance and retreat is hindered and the operating load is increased. Inconvenience such as increase may occur.

The present invention has been made in view of such a point, and an object of the present invention is to provide a double-door storage device capable of stopping the backlash of a rod without hindering its advancement and retreat.

The present invention opens and closes the lid body around a box body having an accommodating portion provided with an opening, a lid body that covers the opening openable and closable, and a first rotation axis extending along the peripheral edge of the opening. A double-door storage device including a first opening / closing mechanism and a second opening / closing mechanism for opening / closing the lid around a second rotation axis extending along the peripheral edge of the opening, wherein the first opening / closing mechanism and the said. The second opening / closing mechanism is provided on the box main body side in response to the rods arranged on the front portion and the rear portion of the lid body so as to be engaged with the box main body side. An engaging portion with which the tip of the rod can be engaged, a first urging member for generating a first urging force for urging the rod in a direction of engaging with the engaging portion, and the first urging member by an opening operation. An operating unit that retracts the rod against the urging force so that the rod is disengaged from the engaging portion, and a second urging force that urges the rod in a predetermined direction different from the advancing / retreating direction of the rod. The second urging member has a second urging member, one end of the second urging member is fixed to the lid, and the other end of the second urging member is fixed to the rod. It is a double-door storage device.

According to this configuration, the second urging member can apply a second urging force to the rod that advances and retreats so as to be engaged with the box body in a predetermined direction different from the advancing / retreating direction of the rod. Occasionally, contact with the main body of the lid can be prevented to prevent backlash between the rod and the lid. In addition, regarding the second urging member required to prevent backlash between the rod and the lid, when the rod moves forward and backward, one end thereof is fixed to the main body of the lid and the other end is integrated with the rod. It can be moved in the forward / backward direction. Therefore, it is avoided that the advancing and retreating of the rod is hindered by the frictional resistance with the second urging member. Therefore, according to the double-door storage device, the backlash of the rod can be stopped without hindering its advancement and retreat.

Next, the operation of the double door storage device 1 will be described.
In the double-door storage device 1, when the lid 20 is closed, the second left side rod 42 projects forward from the front end of the main body of the lid 20, and the first left side rod 41 protrudes rearward from the rear end of the main body of the lid 20. The second right side rod 52 protrudes forward from the front end of the main body of the lid 20, the first right side rod 51 protrudes rearward from the rear end of the main body of the lid 20, and further protrudes from the rear end of the arm member 32. It protrudes backward. In this case, the first left side rod 41 arranged on the lid 20 engages with the arm member 32, and the second left side rod 42 and the second right side rod 52 engage with the front base portion 14 of the box body 10. Then, since the first right side rod 51 engages with the rear base portion 13 of the box body 10 via the arm member 32, the closed state in which the lid 20 closes the opening 11 of the box body 10 is maintained.

When the button portion 45a of the left operation portion 45 is pushed to the right in the closed state of the lid body 20, the mechanism portion 45b abuts on the front end of the second left side rod 42 and pushes the second left side rod 42 rearward. Move to. When the second left side rod 42 moves backward, the left side synchronization device 43 rotates counterclockwise, so that the first left side rod 41 moves forward. When the rearward movement of the second left side rod 42 is performed until the disengagement with the front base portion 14 of the box body 10 is performed, and the forward movement of the first left side rod 41 is performed until the disengagement with the arm member 32, the first The left lock device 40 is in the left unlock state when the first and second right rods 51 and 52 are engaged with the box body 10 (that is, the right lock state of the right lock device 50). In this case, the closed state is held on the right side of the lid 20 and the closed state is released on the left side of the lid 20.

In the left side lock device 40, the disengagement between the second left side rod 42 and the front base portion 14 of the box body 10 and the disengagement between the first left side rod 41 and the arm member 32 are carried out at substantially the same timing. It is desirable that it is configured so as to.

When the left side of the lid 20 is released from the closed state, the lid 20 swings with respect to the arm member 32 by the urging force of the arm spring 35R of the right pivot 33R. Further, when the closed state is held on the right side of the lid body 20, the arm member 32 does not swing with respect to the rear base portion 13 of the box body 10. Therefore, when the button portion 45a of the left operation portion 45 is pressed to the right, the lid body 20 is integrated with the box body 10 and the lid body 20 is connected to the arm member 32 and thus the box body. It rotates about the second rotation axis on the right side with respect to 10. As a result, the left side of the lid 20 is opened toward the open position, and the left side opening operation is automatically performed up to the equilibrium position between the weight of the lid 20 and the urging force of the arm spring 35R.

As shown in FIGS. 9 and 11, the fixing point P between the other end of the left second urging member 46 and the first left rod 41 is the tip of the first left rod 41 with respect to the main body of the lid 20. It is located at position Q1 when the portion (that is, the rear end portion) and the arm member 32 are engaged (that is, the lid 20 is closed or the right side is open), and when the engagement is released (that is, the left side of the lid 20). It is located at position Q2 in the open state). This position Q2 is a position different from the above position Q1, and specifically, it is located on the front side of the position Q1 by the amount of the exit movement of the first left side rod 41. When the fixed point P moves between the position Q1 and the position Q2, that is, when the first left side rod 41 moves forward and backward, the urging force F generated by the left side second urging member 46 is applied to the first left side rod 41. As the rod advances and retreats, the direction to be moved changes within a predetermined range including a direction orthogonal to the advancing and retreating direction of the first left rod 41.

Similarly, the right second urging member 56 is a pulling spring that generates an urging force F that urges the first right rod 51 to the left with respect to the lid 20 (that is, the center side of the lid 20). .. The right side second urging member 56 is held so as to be interposed between the first right side rod 51 and the lid body 20. One end of the right second urging member 56 is fixed to the lower lid member 21 of the lid 20 by a fixing portion 21a. The other end of the right second urging member 56 is fixed to the first right rod 51 at a fixing point P.
