Description

  The present invention relates to a storage device including a box body, a lid that covers an opening of the box body, and an opening / closing mechanism that opens and closes the lid.

  Conventionally, a storage device such as a console box disposed in a vehicle interior is known (for example, Patent Document 1). The storage device includes a box body, a lid, and an opening / closing mechanism. The box body has a housing part with an opening on the upper surface. The lid is formed in a thin rectangular shape corresponding to the opening of the box body, and covers the opening so as to be opened and closed. The opening / closing mechanism has a rotation axis extending along the long side of the periphery of the opening of the box body, and opens and closes the lid body around the rotation axis.

  The opening / closing mechanism has an urging member and a lock member. The biasing member is interposed between the box body and the lid, and generates a biasing force that biases the lid from the closed position toward the fully opened position. The lock member is a member that holds the lid in the closed position against the urging force of the urging member, and holds the lid in the closed position when a predetermined opening operation is performed by a vehicle occupant. It is a member which cancels.

  The opening / closing mechanism also has an extendable arm that connects the box body and the lid. The telescopic arm expands and contracts according to the opening / closing position of the lid. The telescopic arm has a damper as a speed buffer. The damper is an oil damper having a viscous fluid filled between the fixed part and the movable part. This viscous fluid generates a greater resistance force as the speed of the movable part relative to the fixed part increases. For this reason, according to the damper, since the speed of the movable part can be suppressed from changing suddenly, it is possible to mitigate the sudden change in the opening operation of the lid.

And a cam that is integrally attached to one of the box body and the lid, is rotatably supported on either one, and is provided coaxially with the rotating shaft Attached to either the body, the box body, or the lid, slidably contact the surface of the cam body, and the spring force applied to the cam body on the axial side changes according to the opening / closing position of the lid A storage device having a leaf spring.

  According to this configuration, since the spring force by the leaf spring applied from the outer surface to the axial center side on the cam body integrally attached to the box body or the lid body changes according to the opening / closing position of the lid body, According to the spring force, the torque generated when the cam body is rotated with respect to the box body by the urging force of the urging member can be varied. For this reason, at the time of the opening operation from the closed position of the lid to the fully opened position, the opening speed of the lid can be changed by changing the rotational speed of the cam body in the process. In order to realize the opening operation characteristic of the lid, a cam body is provided on the same axis as the rotation shaft, and a leaf spring that is in sliding contact with the outer surface of the cam body may be provided. Therefore, the required opening operation characteristics of the lid can be realized with a simple configuration.

Next, the operation of the storage device 1 will be described.
In the storage device 1, when the lid 20 is closed with respect to the box body 10, the second front lock member 51 of the right lock device 50 has an engaging portion 51 c of the front arm member 31 F by the position adjustment mechanism 60. The position is set to engage with the through hole 38F. When the second front lock member 51 is positioned in this way, the second rear lock member 52 is positioned such that its engaging portion 52c engages with the through hole 38R of the rear arm member 31R via the pinion gear 64. Set to At this time, the engaging portion 51c of the second front locking member 51 and the engaging portion 52c of the second rear locking member 52 remain at the positions inserted up to the central portions of the through holes 38F and 38R, respectively.

  The engagement portion 41b of the first front lock member 41 of the left lock device 40 is inserted into the through hole 38F from the opposite side of the insertion side of the engagement portion 51c of the second front lock member 51. The engagement portion 51c of the second front lock member 51 is in contact with the engagement portion 41b of the first front lock member 41 in the through hole 38F. Further, the engaging portion 42b of the first rear locking member 42 of the left side locking device 40 is inserted into the through hole 38R from the side opposite to the insertion side of the engaging portion 52c of the second rear locking member 52. . The engagement portion 52c of the second rear lock member 52 is in contact with the engagement portion 42b of the first rear lock member 42 in the through hole 38R. In these contact states, both the front arm member 31F and the rear arm member 31R cannot rotate with respect to both the box main body 10 and the lid body 20, and the closed state of the lid body 20 is maintained.

  When the button portion 43a of the left operation portion 43 is pushed in with the lid 20 closed, the convex portion 51f in the guide hole 43d is moved to the inclined portion 43e. In this case, since the second front lock member 51 is moved in the front direction of the vehicle, the first front lock member 41 is pushed out of the through hole 38F of the front arm member 31F and separated by the movement in the vehicle front direction. The At the same time, the second rear lock member 52 is moved by the pinion gear 64 in the rear direction of the vehicle, which is opposite to the moving direction of the second front lock member 51. The side lock member 42 is pushed out from the through hole 38R of the rear arm member 31R and is released.

  When the first front lock member 41 and the first rear lock member 42 are separated from the through holes 38F and 38R, the left-side lock device 40 releases the closed state of the lid 20 on the left side. In this holding release state, the urging force of the torsion coil spring 35FR on the right side of the vehicle causes the cylinder 34FR and the shaft portion 33FR of the front right pivotal portion 32FR of the front arm member 31F to relatively rotate within the support hole 13b of the box body 10, The shaft portion 33RR of the rear right pivot portion 32RR of the rear arm member 31R relatively rotates within the support hole 14b of the box body 10. When this relative rotation occurs, the front arm member 31F rotates with respect to the box body 10 with the shaft portion 33FR as a rotation center, and the rear arm member 31R has a box with the shaft portion 33RR as the rotation center. It rotates with respect to the main body 10. In this case, the lid 20 rotates about the right shaft portion 33-R as the rotation center with respect to the box body 10 in a state of being integrated with the front arm member 31F and the rear arm member 31R. Thereby, the left side of the lid 20 is opened toward the fully open position.

  Further, when the button portion 53a of the right operation portion 53 is pushed in while the lid body 20 is closed, the convex portion 51g in the guide hole 53d is moved to the inclined portion 53e. In this case, since the second front lock member 51 is moved in the vehicle rearward direction, the second front lock member 51 is detached from the through hole 38F of the front arm member 31F. At the same time, the second rear lock member 52 is moved by the pinion gear 64 in the vehicle front direction opposite to the moving direction of the second front lock member 51, so that the second rear lock member 52 is moved to the rear side. The arm member 31R is detached from the through hole 38R.

  When the second front lock member 51 and the second rear lock member 52 are separated from the through holes 38F and 38R, the right-side lock device 50 releases the right-side closed state of the lid 20. Even when the second front lock member 51 and the second rear lock member 52 are separated from the through holes 38F and 38R, the first front lock member 41 is maintained in a state of being engaged with the through hole 38F of the front arm member 31F. In addition, the first rear lock member 42 is maintained in a state of being engaged with the through hole 38R of the rear arm member 31R. In this holding release state, the urging force of the torsion coil spring 35FL on the left side of the vehicle causes the cylinder 34FL and the shaft portion 33FL of the front left pivotal portion 32FL of the front arm member 31F to rotate relative to each other in the support hole 21c of the lid 20, and The shaft portion 33RL of the rear left pivotal portion 32RL of the rear arm member 31R relatively rotates within the support hole 21c of the lid body 20. When this relative rotation occurs, the lid 20 rotates with respect to the front arm member 31F with the shaft portion 33FL as the rotation center, and with respect to the rear arm member 31R with the shaft portion 33RL as the rotation center. Rotate. In this case, the lid 20 rotates about the left shaft portion 33-L as the rotation center with respect to the box body 10 in which the front arm member 31F and the rear arm member 31R are integrated. Thereby, the right side of the lid 20 is opened toward the fully open position.

  As described above, in the storage device 1, the lid 20 can be opened from the closed position covering the opening 11 of the box body 10 toward the left fully opened position with the right shaft portion 33 -R as the rotation center. At the same time, it can be opened toward the right fully open position with the left shaft portion 33-L as the center of rotation. The lid body 20 can be opened and closed by selecting either the right shaft portion 33-R or the left shaft portion 33-L as the center of rotation.

  Since the right shaft portion 33-R is the shaft portion 33FR and the shaft portion 33RR, the opening operation of the lid body 20 to the left fully opened position is the rotation shaft extending along the long side 11a on the vehicle right side of the opening 11 of the box body 10. Is performed around the center of rotation. Further, since the left shaft portion 33-L is the shaft portion 33FL and the shaft portion 33RL, the opening operation of the lid 20 to the right fully open position extends along the long side 11a on the vehicle left side of the opening 11 of the box body 10. The rotation is performed with the rotation axis as the center of rotation. That is, the opening / closing between the closed position and the fully opened position of the lid 20 is performed with the long side of the lid 20 as the center of rotation. If the lid 20 is opened and closed with its long side as the center of rotation, the lid 20 can be opened and closed stably.

  Further, in the storage device 1, a cylindrical body 34FR provided coaxially with respect to the shaft portion 33FR of the right shaft portion 33-R that is a shaft member is formed in a cam shape, and is formed on the outer surface of the cylindrical body 34FR. A leaf spring 37FR that is in sliding contact is provided. The leaf spring 37FR applies a spring force that changes in accordance with a sliding contact position with the cylindrical body 34FR, that is, an opening / closing position from the closed position of the lid body 20 to the fully open position on the left side, with respect to the cylindrical body 34FR. . The opening operation of the lid 20 from the closed position to the left fully opened position is realized by the biasing force of the torsion coil spring 35FR that acts between the cylindrical body 34FR and the front side portion 13 of the box body 10. When the lid 20 is opened from the closed position to the fully open position on the left side, the cylindrical body 34FR of the front arm member 31F is applied with a biasing force by the torsion coil spring 35FR in the rotational direction and a spring force by the leaf spring 37FR. It is given to the axial center side. The spring force by the leaf spring 37FR changes according to the open / close position on the left side of the lid 20 with respect to the box body 10.

  Thus, if the spring force by the leaf spring 37FR applied to the cylinder body 34FR from the outer surface to the axial center side changes, the cylinder body 34FR is biased by the torsion coil spring 35FR in accordance with the spring force by the leaf spring 37FR. Thus, it is possible to change the torque by changing the rotation resistance generated when the box body 10 is rotated. Note that the change in the rotational resistance and the change in the torque are specifically due to a component force corresponding to the contact angle (that is, the cam slope angle) between the cylindrical body 34FR and the leaf spring 37FR among the spring force of the leaf spring 37FR. It depends on the frictional resistance. For this reason, when the lid 20 is opened from the closed position to the fully open position on the left side, the rotational speed of the cylinder 34FR changes in the process, so that the opening speed of the lid 20 can be changed.

  For example, when the cam shape of the cylindrical body 34FR is set so that the spring force of the leaf spring 37FR is minimized at the closed position of the lid body 20 and maximized at the fully open position on the left side of the lid body 20. In the opening operation from the closed position to the left fully opened position, the cylinder 34FR starts to rotate with respect to the box body 10 at a relatively high rotation speed in the process, and then the rotation speed gradually decreases and the left side Slowest immediately before the fully open position. In this case, since the opening speed of the lid 20 to the left fully opened position shows a change according to the rotation speed of the cylindrical body 34FR, the opening speed of the lid 20 can be reduced as it approaches the left fully opened position. it can.

  Similarly, in the storage device 1, a cylindrical body 34FL provided coaxially with respect to the shaft portion 33FL of the left shaft portion 33-L which is a shaft member is formed in a cam shape, and the outer surface of the cylindrical body 34FL A leaf spring 37FL is provided in sliding contact therewith. The leaf spring 37FL applies a spring force that changes in accordance with a sliding contact position with the cylinder 34FL, that is, an open / close position from the closed position of the lid 20 to the fully open position on the right side, with respect to the cylinder 34FL. . The opening operation of the lid 20 from the closed position to the right fully opened position is realized by the biasing force of the torsion coil spring 35FL that acts between the cylinder 34FL and the lid 20. When the lid 20 is opened from the closed position to the right fully opened position, the cylindrical body 34FL of the front arm member 31F is given a biasing force by the torsion coil spring 35FL in the rotation direction and a spring force by the leaf spring 37FL. It is given to the axial center side. The spring force by the leaf spring 37FL changes according to the opening / closing position on the right side of the lid 20 with respect to the box body 10.

  Thus, if the spring force by the leaf spring 37FL applied to the cylindrical body 34FL from the outer surface to the axial center side changes, the torsion coil spring 35FL acts on the tubular body 34FL in accordance with the spring force by the leaf spring 37FL. The torque can be varied by changing the rotational resistance generated when the lid 20 is rotated by the urging force. The change in the rotational resistance and the fluctuation in the torque are specifically caused by a component force corresponding to the contact angle (that is, the cam slope angle) between the cylindrical body 34FL and the plate spring 37FL among the spring force of the plate spring 37FL. It depends on the frictional resistance. For this reason, during the opening operation from the closed position of the lid 20 to the right fully opened position, the rotational speed of the cylinder 34FL changes in the process, so the opening speed of the lid 20 can be changed.

  For example, when the cam shape of the cylinder 34FL is set so that the spring force of the leaf spring 37FL is minimized at the closed position of the lid 20 and maximized at the right-side fully opened position of the lid 20. During the opening operation from the closed position to the right fully opened position, the lid body 20 starts to rotate with respect to the cylinder 34FL at a relatively high rotation speed in the process, and then the rotation speed gradually decreases and the right side Slowest immediately before the fully open position. In this case, since the opening speed of the lid 20 to the right fully opened position shows a change according to the rotation speed of the cylinder 34FL, the opening speed of the lid 20 can be reduced as it approaches the right fully opened position. it can.

  Therefore, according to the storage device 1, desired characteristics can be realized as the opening operation characteristic from the closed position of the lid 20 to the left fully opened position, and the opening operation from the closed position of the lid 20 to the right fully opened position is achieved. A desired characteristic can be realized as a characteristic. For this reason, a feeling of hospitality, a high-class feeling, etc. can be produced about the opening operation of the lid 20.

  Further, in order to realize a desired characteristic as the opening operation characteristic of the lid body 20 as described above, the shapes of the cylinders 34FL and 34FR of the front arm member 31F are formed in accordance with the required opening operation characteristic of the lid body 20. The leaf springs 37FL and 37FR attached to and fixed to the box body 10 or the lid 20 may be brought into sliding contact with the outer surfaces of the cylinders 34FL and 34FR. Therefore, the required opening operation characteristic of the lid 20 can be realized at a low cost with a simple configuration.

That is, the spring force by the leaf springs 37FL and 37FR is minimized at the closed position of the lid 20 and maximized at the fully opened position of the lid 20. However, the present invention is not limited to this. The cam shapes of the cylinders 34FL and 34FR are formed so that the cam height in the circumferential position of the cam surface decreases from the closed position to the fully opened position of the lid 20 in accordance with the desired opening operation characteristics of the lid 20.
