[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automobile door pocket.
[0002]
[Prior art]
Inside the door of the car, a door pocket is attached so that small items such as maps can be put. There is an open / close type of the door pocket which allows the stored items inside the door pocket to be taken out by opening / closing the door pocket. One end of this open / close type door pocket is pivotally attached to the door trim. The door pocket is held closed by a turnover spring that reverses depending on the opening / closing angle and generates a biasing force in the closing direction or opening direction. ing.
[0003]
[Problems to be solved by the invention]
However, especially when a relatively heavy object such as a map or magazine is placed inside the door pocket, if you close the door strongly, the turnover spring will reverse due to the impact and the door pocket will open carelessly. There was a thing. In addition, when the car suddenly cornered, the same thing happened due to the action of gravity.
[0004]
In view of the above, the present invention provides an automobile door pocket that does not open carelessly due to an impact applied to the vehicle body even when a relatively heavy object is stored in the door pocket. This is a problem.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the storage portion provided on the inner surface of the door, the pocket pivotally supported by the storage portion, and the pocket are stored in the storage portion. In the automobile door pocket having the biasing means for biasing the pocket, the pocket is placed from the storage position against the biasing force of the biasing means while a predetermined inertial force is applied to the storage body on the storage portion. A holding means for preventing the opening is provided.
[0006]
According to this structure, the pocket pivotally supported by the storage part provided in the inner surface of the motor vehicle is normally urged | biased so that it may be accommodated in a storage part by the urging means. However, in this state, when a predetermined inertial force, that is, an inertial force larger than the urging force of the urging means, acts on the vehicle body, the inertial force overcomes the urging force of the urging means and the pocket opens from the storage portion. And
[0007]
At this time, the holding means provided in the storage portion prevents the pocket from opening from the storage position while a predetermined inertial force is acting on the vehicle body. For this reason, when a predetermined inertia force acts on the vehicle body, the pocket can be prevented from being inadvertently opened from the storage position. Further, when the inertial force is lost, the holding means automatically releases the pocket, so that it is not necessary to perform a releasing operation every time the holding means is activated.
[0008]
Further , the holding means is pivotally supported by the storage portion, and is formed on a hook member capable of locking the hook portion provided in the pocket, and a predetermined inertia force is applied to the vehicle body formed on the shaft portion of the hook member. At this time, the weight portion is configured to rotate the hook member in the direction in which the hook portion is locked, and the spring member is configured to retract the hook member from the hook portion when a predetermined inertia force is not applied.
[0009]
According to this configuration, the hook member is pivotally supported by the storage portion, and the spring member retracts the hook member from the hook portion provided in the pocket by its elastic force. For this reason, in a normal pocket opening / closing operation, the hook member does not lock the hook portion. Here, when a predetermined inertial force acts on the pocket, the weight portion formed on the shaft portion moves, and the hook member rotates in a direction to lock the hook portion, thereby locking the hook portion. For this reason, it is possible to prevent the pocket from being inadvertently opened from the storage position.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the automobile door pocket 10 is provided on the door trim 14 (inner side surface of the door) of the side door 12 and is positioned below the armrest 16. Hereinafter, an automobile door pocket according to the present embodiment will be described in detail with reference to the accompanying drawings.
[0011]
As shown in FIGS. 2 and 3, the automobile door pocket 10 includes a storage frame 18 attached to the door trim 14, a pocket portion 20 </ b> A that pivotally supports the storage frame 18 and constitutes a pocket 20, and a pocket A turnover spring 22 (hereinafter simply referred to as a spring 22) as an urging means for urging the portion 20A in the opening direction or the closing direction, and the pocket 20 from the storage position while a predetermined inertial force is acting on the vehicle body. It is comprised from the latching tool 24 as a holding means which blocks | prevents opening, and the cover 20B which covers the surface of the pocket part 20A.
[0012]
Here, the storage frame 18 is formed in a U shape, and is fixed to the door trim 14 by a fastener such as a bolt and a nut. And the shaft pin 23 (refer FIG. 4) of the pocket part 20A is pivotally supported by the groove | channel 34A of the hinge board 34 provided in the lower part of the storage frame 18 so that rotation is possible.
[0013]
Further, a damper (not shown) is disposed on the back surface of the storage frame 18, and a damper gear 28 attached to the damper is exposed from the recess 47 of the storage frame 18. The damper gear 28 meshes with a rack 30 formed in the pocket portion 20 </ b> A, and keeps the opening speed of the pocket 20 from the storage frame 18 constant.
[0014]
As shown in FIGS. 4 and 5, the pocket 20 is biased by a spring 22 having one end attached to the guide pin 33 of the pocket portion 20 </ b> A and the other end attached to the bracket 21 of the storage frame 18. . The spring 22 urges the guide pin 33 in the direction of arrow A when the pocket 20 is stored in the storage frame 18, and prevents the pocket 20 from opening from the storage frame 18 due to a light impact or the like.
[0015]
On the other hand, when the pocket 20 is opened to a predetermined angle while moving the guide pin 33 along the guide hole 37 formed in the storage frame 18, the spring 22 is reversed as shown in FIG. The guide pin 33 is urged in the direction to automatically fully open. A grip portion 36 is attached to the upper portion of the cover 20B in consideration of ease of gripping when opening and closing the pocket (see FIG. 2).
[0016]
Next, the structure of the locking tool 24 will be described in detail.
[0017]
As shown in FIGS. 2 and 4, the locking tool 24 is attached to the back surface of the storage frame 18, and the hook member 42 constituting the locking tool 24 is exposed from the insertion groove 32 formed on the side surface of the storage frame 18. is doing. As shown in FIG. 6, a shaft hole 27 is formed in the stepped shaft portion 54 of the hook member 42, and the shaft hole 27 extends to the rod-shaped mounting pin 38 formed on the back surface of the storage frame 18. It is inserted. As a result, the hook member 42 can be rotated around the mounting pin 38.
[0018]
Further, a claw portion 56 that locks the L-shaped hook portion 40 formed in the pocket portion 20 </ b> A is formed at the distal end portion of the hook member 42. Further, a weight portion 44 is provided on the upper portion of the shaft portion 54, and the hook member 42 rotates downward about the mounting pin 38 when an inertial force is applied by increasing the position of the center of gravity of the locking tool 24. It comes to move.
[0019]
Further, a coil spring 46 is attached to the stepped shaft portion 54. That is, the winding portion 60 of the coil spring 46 wound in a coil shape is fitted into the small diameter portion of the stepped shaft portion 54, the one end portion 62A pushes up the weight portion 44 from below, and the other end portion 62B The insertion groove 32 is locked to the notch 48. For this reason, the weight portion 44 always receives an elastic force so as to be supported from the one end portion 62A. At this time, the weight portion 44 is positioned in contact with the holding plate 50 formed on the storage frame 18 so as not to rotate in the reverse direction (see FIG. 8). The rotation direction is limited by the holding plate 50 so that the hook member 42 does not rotate in the direction opposite to the direction in which the hook portion 40 is locked by an impact acting on the vehicle body.
[0020]
The winding portion 60 has no interference between the wire rods and has a slightly larger diameter than the small-diameter portion of the shaft portion 54. In order to improve stability at the time of contact, the ends of the end portions 62A and 62B are respectively It is curved inward. Further, it is appropriate that the effective winding number of the winding part 60 is 7.15 and the spring constant of the coil spring 46 is 0.83 kg · mm / degree.
[0021]
Next, the operation of the automobile door pocket 10 will be described in detail.
[0022]
When a predetermined inertia force is not applied to the vehicle body, when the pocket 20 is stored in the storage frame 18, the spring 22 is biased in the direction in which the pocket 20 is stored. Due to the vibration, the pocket 20 does not open from the storage frame 18.
[0023]
However, in particular, when a relatively heavy book such as a map is stored in the pocket 20, the impact generated from the outside on the vehicle body, the centrifugal force generated during sudden cornering, and the inertial force (moment of inertia) of the book, etc. As a result of overlapping and acting on the pocket 20 as a larger inertia force (predetermined inertia force), the pocket 20 is opened by overcoming the elastic force of the spring 22.
[0024]
Here, when the predetermined inertial force as described above acts on the pocket 20, the weight portion 44 overcomes the urging force (elastic force) of the coil spring 46 before the pocket 20 is opened, as shown in FIG. The hook portion 40 is guided in the locking direction, and the hook member 42 is rotated around the mounting pin 38. And since the nail | claw part 56 of the hook member 42 latches the hook part 40, the pocket 20 does not open from an accommodation position carelessly.
[0025]
Next, when the inertial force becomes a predetermined value or less, the weight portion 44 is pushed up by the urging force of the coil spring 46 and returned to the original state (the state shown in FIG. 4) again. Therefore, since the locking tool 24 automatically releases the pocket 20, there is no need to perform a releasing operation every time the locking tool 24 is operated. In this state, the pocket 20 can be opened by hand, and a normal opening / closing operation is possible. Further, since the pocket 20 is biased in the closing direction by the spring 22, it does not open carelessly.
[0026]
As another embodiment, the above embodiment has been described in the case where the number of turns of the coil spring 46 attached to the hook member 42 is 7.15 and the spring constant is 0.83 kg · mm / degree. Instead, the number of turns of the coil spring 46 may be appropriately changed in relation to the weight of the weight portion 44 and the magnitude of the inertial force.
[0027]
As a rule of thumb, the bending moment required when the coil spring 46 is attached is 90 kg · mm, and the bending moment at the maximum load that the coil spring 46 can withstand is 114 kg · mm.
[0028]
Further, in the above description, the locking device 24 is provided on one rear surface of the storage frame 18, but the present invention is not limited to this, and the same is applied to both rear surfaces of the storage frame 18 in order to sufficiently lock the pocket 20. The hook portion 40 of the pocket 20 is preferably formed on both side surfaces of the pocket portion 20A correspondingly.
[0029]
【The invention's effect】
According to the automobile door pocket according to the present embodiment, the holding means is provided in the storage portion, so that the pocket can be prevented from opening from the storage position while a predetermined inertial force is acting on the vehicle body. Further, when the predetermined inertia force is lost, the holding means automatically releases the pocket, so that it is not necessary to perform a releasing operation every time the holding means is operated.
