  The invention according to claim 9 is characterized in that the damper device is provided on a side portion of the box body in the front-rear direction.

  According to the first aspect of the present invention, the shaft members of the pair of support portions of the left and right opening / closing mechanisms are rotatably fitted to the bearing portions provided on the box body. In addition, the lock member is movably accommodated in the accommodating portion inside the shaft member. The lock member is urged in a direction to advance into a lock hole provided in the lid member. For this reason, the lock member is engaged with the lock hole, and the lid member maintains a state where the recess is closed.

  Further, when the slide member is advanced into the lock holes of the pair of support portions of either the left or right opening / closing mechanism, the slide member pushes the lock member out of the lock hole and releases the engagement of the lock member with the lock hole. . Thereby, either the left or right side of the lid member can be opened. On the other hand, the lock members of the pair of support portions of the left and right other opening / closing mechanisms are maintained in engagement with the lock holes. For this reason, by lifting one of the left and right sides of the lid member, the shaft members of the pair of support portions of the other opening / closing mechanism on the left and right sides rotate with respect to the bearing portion, and one of the left and right sides of the lid member opens.

  Here, the shaft member is rotatably fitted to a bearing portion provided in the box body. Further, the lid member is attached to and detached from the box body by the lock member housed in the housing portion in the shaft member engaging or disengaging from the lock hole provided in the lid member. That is, in the present invention, the rotation function of the lid member is borne by the bearing portion and the shaft member, and the detachment function to the lid member side is borne by the lock member and the lock hole. Since the rotation function and the detachment function are carried by separate members, the load received when the lid member is opened and closed can be shared by the separate members, and concentration of the load can be avoided.

  A lock member is movably accommodated inside the shaft member. For this reason, the thickness of a shaft member becomes large and the rigidity around the axis | shaft of a shaft member becomes high compared with the conventional shaft pin. Therefore, the strength of the shaft member is increased with respect to the load received during rotation, particularly the load in the torsional direction.

  The shaft member is attached to the box body side. For this reason, compared with the case where an axial pin is assembled | attached in a cover member like the past, the number of parts assembled | attached in a cover member decreases. In addition, after the lock member is accommodated in the accommodating portion of the shaft member, the shaft member may be fitted into the bearing portion, and the assembling property of the parts is improved as compared with the conventional case.

  According to the second aspect of the present invention, the lock member is engaged with the lock hole of the lid member so as to rotate together with the lid member. For this reason, the load of the lid member at the time of rotation is transmitted to the highly rigid shaft member via the lock member. Therefore, when the lid member is rotated, the lid member is supported by the highly rigid shaft member, and the strength of the lid member during the rotation is improved.

  According to the third aspect of the present invention, the accommodating portion and the lock hole are opened in a shape that matches the non-circular cross section of the lock member. For this reason, the positional displacement of the circumferential direction of the lock member with respect to the accommodating part and the lock hole is regulated. Therefore, when the lid member rotates, the lock member and the shaft member also rotate. Therefore, the load of the lid member at the time of rotation is transmitted to the shaft member via the lock member. Therefore, when the lid member is rotated, the lid member is supported by the shaft member having high rigidity, and the strength of the lid member at the time of rotation is improved.

  According to the fourth aspect of the present invention, the position adjusting means provided in the pair of support portions adjusts the position of the shaft member in the circumferential direction to the engagement position where the lock member engages with the lock hole of the lid member. To do. For this reason, the circumferential position of the non-circular cross section of the lock member coincides with the circumferential position of the lock hole, and the lock member can be reliably engaged with the lock hole.

  According to the fifth aspect of the present invention, the position adjusting means biases the shaft member so as to be positioned at the engagement position. For this reason, when the lid member is opened and the engagement between the lock member and the lock hole of the lid member is released, the rotational force of the lid member is not transmitted to the shaft member, and the shaft member is held in the engaged position. Is done. Therefore, when closing the lid member, the lock member accommodated in the shaft member can always engage the lock hole.

  According to the sixth aspect of the present invention, when the lid member is closed from the opened state, the opening peripheral edge of the lock hole of the lid member abuts on the taper surface of the lock member, and the lock member is moved to the accommodating portion side. Retreat. By further closing the lid member, the positions of the lock member and the lock hole coincide with each other, and the lock member once retracted enters the lock hole and engages. By providing the lock member with the tapered surface in this way, the lock member is pushed by the lid member and retracts from the lock hole, so that the lid member can be reliably closed without obstructing the lid member.

  According to the seventh aspect of the present invention, the opening / closing speed of the lid member can be moderately suppressed, and the operability during opening / closing is improved.

  According to the eighth aspect of the present invention, the position adjusting means is provided on the side of the box body in the front-rear direction. When the double-folded storage box of the present invention is used as a vehicle interior part, the side part in the front-rear direction of the box body is a part that is covered with other vehicle body interior parts and is not visible to the vehicle occupant. By disposing the position adjusting means on the side of the box body in the front-rear direction, the position adjusting means is not visually seen. In addition, the portion of the box body that is not viewed from the outside can be used effectively.

  Next, the operation of the double storage box according to this embodiment will be described. First, the state of each component when the lid member 2 closes the recess 10 of the box body 1 will be described. As shown in FIG. 8, when the lid member 2 closes the recess 10 of the box body 1 and is in the closed position, the lock members 55 of the pair of support portions 51 and 52 of the opening and closing mechanisms 31 and 32 on both the left and right sides are attached. The force member 56 advances into the lock hole 54 of the lid member 2 and engages with the lock hole 54. At this time, the lid member 2 is held on the box body 1 side by the engagement of the lock member 55 with the lock hole 54. For this reason, the lid member 2 cannot be lifted even if one of the left and right sides of the lid member 2 is gripped and pushed upward.

  When the lid member 2 is closed in this way, the other end 72b of the spring 72 provided on the retaining member 71 is in contact with the stopper 12 protruding from the side portion 11 of the box body 1 as shown in FIG. In contact therewith, the rotation of the spring 72 is restricted. The other end 72b of the spring 72 is fixed to the retaining member 71, and the retaining member 71 is regulated in the circumferential direction with respect to the shaft member 53. For this reason, the shaft 72 is adjusted to a predetermined circumferential position with respect to the box body 1 by the spring 72 coming into contact with the stopper 12. As shown in FIGS. 4 and 5, the predetermined circumferential position is a position where one side of the square section of the accommodating portion 53 c provided in the shaft member 53 faces in the horizontal direction. When the shaft member 53 is adjusted to the predetermined circumferential position, one side of the square section of the body portion 55a of the lock member 55 housed in the housing portion 53c also faces in the horizontal direction. The lock hole 54 having a square cross section formed in the lid member 2 has one side facing the horizontal direction when closed. For this reason, the accommodating part 53c, the lock member 55, and the lock hole 54 of the shaft member 53 have one side of each cross-sectional square oriented in the horizontal direction.

  Next, as shown in FIG. 10, when the operation member 61 of the operation unit 6 of the opening / closing mechanism 31 provided on the right side of the lid member 2 is pushed into the lid member 2, the operation member 61 is brought into the lid member 2. Moving. The inclined portion 61 b of the operation member 61 pushes the slide member 57 toward the outside in the front-rear direction of the recess 10 while slidingly contacting the sliding contact member 58. The slide member 57 advances into the lock hole 54 against the urging force of the coil spring 57d. The lock member 55 engaged with the lock hole 54 comes into contact with the distal end portion 57a of the slide member 57 at the distal end portion of the trunk portion 55a. The front end portion 57 a of the slide member 57 pushes the lock member 55 out of the lock hole 54 while entering the lock hole 54, thereby releasing the engagement of the lock member 55 with the lock hole 54. The operation member 61 is brought into contact with the inner end surface of the L-shaped guide wall 22c provided on the lid member 2, and movement is restricted. At this time, the slide of the front end portion 57 a of the slide member 57 stops at the opening of the lock hole 54. Thereby, the lid member 2 is released from the lock member 55 held on the box body 1 side. Thus, by pushing the operating member 61 of the right opening / closing mechanism 31 into the lid member 2, the right side of the lid member 2 is released from the lock member 55 provided on the right side of the recess 10. In this state, as shown by an arrow A in FIG. 9, the right side portion of the lid member 2 is gripped and lifted upward so that the lid member has the support portions 51 and 52 of the left opening / closing mechanism 32 as the rotation center. 2 rotates, the left side of the lid member 2 opens, and the lid member 2 takes the open position.

  Here, as shown in FIG. 11, a retaining member 71 to which the other end 72 b of the spring 72 is fixed is integrally fixed to the shaft member 53 of the pair of support portions 51 and 52 of the left opening / closing mechanism 32. Yes. For this reason, when the right side of the lid member 2 is opened, the retaining member 71 of the left opening / closing mechanism 32 rotates in a direction away from the stopper 12 protruding from the box body 1 against the biasing force of the spring 72. On the other hand, the spring 72 wound around the retaining member 71 of the right opening / closing mechanism 31 is kept in contact with the stopper 12 protruding from the side portion 11 of the box body 1 by its biasing force. Therefore, as shown in FIG. 4, the circumferential position of the shaft member 53 of the right opening / closing mechanism 31 is held at a predetermined position where the lock member 55 having a square cross section is engaged with the lock hole 54. That is, the circumferential position of the shaft member 53 is held at a predetermined position, and the housing portion 53c provided in the shaft member 53 and the square section of the lock member 55 housed in the housing portion 53c. One side faces in the horizontal direction, and the taper surface 55c of the lock member 55 faces upward.

  Next, when closing the lid member 2 whose right side is open, the right side portion of the lid member 2 is pushed downward. At this time, the circumferential position of the shaft member 53 is held at a predetermined position as described above, and the taper surface 55c of the lock member 55 faces upward. For this reason, the lower surface on the right side of the lid member 2 abuts against the tapered surface 55c of the body portion 55a of the lock member 55, and the body portion 55a of the lock member 55 resists the urging force of the urging member 56. Is pushed back into. Eventually, the side surface of the step portion 20 of the lid member 2 descends from the front end surface of the trunk portion 55a, and the lock hole 54 opened to the step portion 20 of the lid member 2 is as high as the front end surface of the trunk portion 55a. Located in. At this time, the lock member 55 enters the lock hole 54 by the urging force of the urging member 56. The tip of the lock member 55 is retracted from the lock hole 54 by pushing the tip portion 57 a of the slide member 57 in the lock hole 54. Thereby, the lock member 55 is engaged with the lock hole 54 of the lid member 2, and the lid member 2 is pivotally supported on the box body 1 side.

  In the present embodiment, as shown in FIG. 5, the shaft member 53 is rotatably fitted to the box body 1, and is attached to and detached from the lid member 2 by a lock member 55 accommodated in the shaft member 53. Is engaged or disengaged from a lock hole 54 provided in the lid member 2. That is, in the present embodiment, the pivot function of the lid member 2 is assigned to the shaft member 53 and the bearing portion 50, and the detachment function to the lid member 2 side is assigned to the lock member 55 and the lock hole 54. Since the rotation function and the detachment function are carried by separate members, the load received when the lid member 2 is opened and closed can be shared by the separate members, and concentration of the load can be avoided.

  Moreover, the accommodating part 53c of the shaft member 53 accommodates the lock member 55 in a movable manner. For this reason, the thickness of the shaft member 53 is increased, and the rigidity around the shaft of the shaft member 53 is higher than that of the conventional shaft pin. Therefore, the strength of the shaft member 53 is increased with respect to the load received during rotation, particularly the load in the twisting direction.

  The shaft member 53 is attached to the box body 1 side. For this reason, compared with the case where an axial pin is assembled | attached in a cover member like the past, the number of parts assembled | attached in the cover member 2 decreases. Further, after the lock member 55 is accommodated in the accommodating portion 53c of the shaft member 53, the shaft member 53 may be fitted into the bearing portion 50, and the assembling property of the parts is improved as compared with the conventional case.

  Further, as shown in FIG. 4, the cross-sectional shape of the lock member 55 is a non-circular shape similar to the lock hole 54 of the lid member 2. For this reason, the positional displacement of the lock member 55 in the circumferential direction with respect to the lock hole 54 is restricted, and the lock member 55 rotates together with the lid member 2. The load of the lid member 2 at the time of rotation is transmitted to the highly rigid shaft member 53 via the lock member 55. Therefore, when the lid member 2 is rotated, the lid member 2 is supported by the shaft member 53 having high rigidity, and the strength of the lid member 2 during rotation is improved.

  Further, the circumferential position of the shaft member 53 is maintained by the spring 72 so that one side of the cross-sectional square of the housing portion 53c of the shaft member 53 faces in the horizontal direction. One side of the square section of the trunk portion 55a of the lock member 55 housed in the housing portion 53c is also maintained in the horizontal direction. For this reason, the taper surface 55c formed at the tip of the body portion 55a of the lock member 55 always faces upward. For this reason, when the lid member 2 rotates from the open position to the closed position, the tapered surface 55 c comes into contact with the bottom surface of the lid member 2, and the lock member 55 is temporarily retracted into the accommodating portion 53 c of the shaft member 53. . Therefore, the lid member 2 can be pushed down to the closed position without being blocked by the lock member 55.

  When the lid member 2 is pushed down to the closed position, one side of the cross-sectional square of the lock hole 54 provided in the lid member 2 is in the horizontal direction. For this reason, the circumferential position of the lock member 55 coincides with the circumferential position of the lock hole 54, and the lock member 55 can be reliably engaged with the lock hole 54.

  As shown in FIG. 5, a damper device 74 is provided on the support portion 51 on the rear side of the opening / closing mechanisms 31 and 32 on both the left and right sides. The gear portion 74 c of the damper device 74 meshes with a gear portion 71 e provided on the retaining member 71. The retaining member 71 is integrally fixed to the shaft member 53 in a state where rotation in the circumferential direction is restricted with respect to the shaft member 53 by the engaging portion 71b. For this reason, the rotational speed of the shaft member 53 is moderately suppressed by the damper device 74 together with the retaining member 71. Therefore, when the lid member 2 is opened and closed, the lid member 2 can be prevented from rotating suddenly, and a feeling of operation is good.

  Further, the opening 50 b at the other end in the axial direction of the bearing portion 50 is formed in the side portion 11 in the front-rear direction of the box body 1. The side 11 of the box body 1 is covered with the center console and is not visible to the vehicle occupant. By disposing the retaining member 71, the spring 72, and the damper device 74 on the side portion 11 in the front-rear direction of the box body 1, these components are not visually seen. Further, the portion of the box body 1 that is not viewed from the outside can be used effectively.

  In the present embodiment, the damper device 74 is provided only on the support portion 52 on the rear side of the opening / closing mechanisms 31 and 32 on both the left and right sides, but may be provided on the support portion 51 on the front side, or support on both the front and rear sides. You may provide in the parts 51 and 52. FIG.

  Moreover, in this embodiment, although the cross-sectional shape of the accommodating part 53c of the shaft member 53, the lock member 55, and the lock hole 54 of the cover member 2 is square, there is no limitation in particular if it is non-circular. For example, it may be a polygon such as a triangle, a rectangle, or a hexagon, or an ellipse, or it may be a shape having irregularities on at least a part of a circle.
