[0003]
By the way, as a bullet urging means for giving an opening force to the lid, for example, as disclosed in Japanese Utility Model Laid-Open No. 62-43846, a compression coil is provided between a piston bottom surface and a cylinder bottom slidingly engaged with a cylinder. 2. Description of the Related Art There is known a thrust generating device in which a spring is contracted to give an extrusion force to a piston. Further, as a lock mechanism for the alternate operation, for example, as disclosed in Japanese Patent Laid-Open No. 3-197782, a heart cam that alternately locks / frees by pushing the free end of the lid in one direction is used. Is frequently used.
[0004]
[Problems to be solved by the invention]
Now, if an opening force is applied to the lid by the piston-type thrust generating device, the width of the entire storage device tends to increase because the device must be disposed on the side of the case forming the article storage portion. It becomes. Moreover, it is customary to provide the same device only on one side of the lid not only due to dimensional convenience but also due to manufacturing cost, but according to this, it can be avoided that the opening operating force becomes unbalanced. Absent.
[0005]
The present invention has been devised to eliminate such disadvantages of the prior art, and its main purpose is to provide a compact structure and good operability for an article storage device with a lid. It is in.
[0006]
[Means for Solving the Problems]
According to the present invention, such a purpose can be rotated about a box-shaped case (inner case 3) having an open front surface and an axis extending in the width direction at lower portions of both side walls of the case. Thus, in the state where it is pivotally supported and opened, a configuration of an article storage device for an automobile having a lid (4) in which a lower portion from the center in the vertical direction is accommodated at a position facing the outer surface of the lower wall of the case. A rod (10) having one end connected to the central portion in the width direction of the portion located on the lower end side when the lid is closed and provided with a rack gear (13) , and receiving the rod in a linearly movable manner. And a rod receiver (case 8) connected to the case, and a coil spring provided between the rod and the rod receiver and constantly elastically energizing the rod so as to be immersed in the rod receiver. (17) and And locking means for holding the protruding state from the rod receptor serial rod (heart cam 18, guide pin 20), a pinion (14) rotating in mesh with the rack gear and to impart a rotational resistance to the pinion the rod This is achieved by arranging the lid driving unit (6) comprising the rotational resistance applying means (damper 11) provided in the receiver at a position adjacent to the outer surface of the lower wall of the case .
[0007]
[Action]
According to such a configuration, when the lid is opened, a part of the lid overlaps with the outer surface of the lower wall of the case. Therefore, the amount of protrusion of the lid from the plane with which the opening of the case comes into contact when the lid is opened is reduced. Further, since the lid driving unit including the coil spring for opening bias, the locking means for holding and closing, and the damper for adding resistance to the opening operation is disposed adjacent to the outer surface of the lower wall of the case, the entire apparatus can be made compact. . Moreover Runode the coil spring is arranged to with the opening direction urging the lid in the axial direction intermediate portion of the rotational axis of the lid, the balance of the opening force acting on the lid is improved.
[0008]
【Example】
Hereinafter, the configuration of the present invention will be described in detail based on specific embodiments shown in the accompanying drawings.
[0009]
FIG. 1 shows a vamp 1 for a vehicle constructed according to the invention. For example, the suction cup 1 is attached below the air conditioning control device C and the audio device D of the center console B provided at the center of the instrument panel A of the passenger car shown in FIG.
[0010]
The suction cup 1 includes an outer case 2 fixed to the inside of the console panel, and an inner case 3 received in the outer case 2 and configured to be detachable from the outer case 2.
[0011]
The inner case 3 has a box shape that is long and relatively deep in the width direction with the front surface open, and a lid 4 is pivotally attached to lower portions of the two side walls facing each other. The lid 4 is pivotally supported by the inner case 3 so as to be rotatable about an axis extending in the width direction at a position deviated slightly from the center in the height direction of the lid 4 in the closed state. The upper free end is pivoted and opened to the front side. Here, as shown by an imaginary line in FIG. 1, the lid 4 is opened in a gap 5 defined between opposed surfaces of the lower wall inner surface of the outer case 2 and the outer surface of the lower wall of the inner case 3. The lower part from the central part is accommodated, and a part of the lid 4 overlaps the outer surface of the lower wall of the inner case 3.
[0012]
An opening force is applied to the lid 4 between the central portion in the width direction on the lower end side of the inner surface of the lid 4 and the outer surface of the bottom wall of the inner case 3 at a position adjacent to the outer surface of the lower wall of the inner case 3 and its operating speed. A lid driving unit 6 is provided for appropriately setting. A rib 7 is provided on the lower wall of the inner case 3 to protect the lid drive unit 6 when the inner case 3 is taken out from the outer case 2.
[0013]
As shown in FIGS. 3 to 6, the lid drive unit 6 includes a vertically long case 8, a rod 10 that is slidably fitted in a vertically extending rod receiving portion 9 that is provided in the case 8, and an appropriate position on the side surface of the case 8. And a rotational resistance imparting damper 11 provided in A connecting projection 12 projecting from the lower end of the case 8 is pivotally supported on the bottom wall of the inner case 3, and the upper end 10a of the rod 10 protruding from the upper end of the case 8 is formed on the inner surface of the lid 4 in the closed state. It is pivotally supported at a position deviating downward from a portion covering the opening of the inner case 3.
[0014]
A rack gear 13 is provided on one surface of the rod 10 and meshes with the pinion 14 of the rotation resistance imparting damper 11. Thereby, an appropriate sliding resistance is given to the rod 10.
[0015]
A spring receiving seat 15 protrudes from the lower end of the rod 10. The spring receiving seat 15 protrudes into an upper closed spring receiving portion 16 provided in the case 8 in parallel with the rod receiving portion 9, and the upper surface of the spring receiving seat 15 and the upper wall of the spring receiving portion 16. A compression coil spring 17 is contracted between the inner surface (FIGS. 5 and 6). Thereby, the elastic urging force in the pull-in direction always acts on the rod 10. In the case of the main suction case 1, the pulling direction of the rod 10 and the opening direction of the lid 4 coincide with each other, so that the urging force in the opening direction always acts on the lid 4.
[0016]
The other surface of the rod 10 is formed with a cam groove 19 whose lower end portion forms a heart cam 18 as a part of the locking means .
[0017]
On the cam groove side wall of the upper end portion of the case 8, a guide pin 20 whose free end projects into the cam groove 19 and forms a part of the locking means is provided. The guide pin 20 is elastically biased by a spring member 21 attached to the outer surface of the case 8 in a direction in which the free end enters the cam groove 19.
[0018]
Next, the operation procedure of the above embodiment will be described with reference to FIG. When the upper end of the lid 4 is pushed in the closed position shown by the solid line in FIG. 1, there is a step where the left groove becomes deeper at the bottom of the lock portion 18 a of the groove of the heart cam 18. As shown by the arrow in FIG. 7, the lock unit 18a is skewed to the left side. When the left and right upper and lower grooves are reached, the tip of the guide pin 20 cannot return to the locked position, and the lock is released. When the locked state is released, the rod 10 is retracted by the elastic force of the compression coil spring 17, and accordingly, the lid 4 rotates its upper end to the near side, thereby realizing an open state indicated by an imaginary line. At this time, the rotational resistance imparting damper 11 is rotated via the pinion 14 meshed with the rack gear 13 provided on the rod 10, and the opening speed of the lid 4 is controlled to an appropriate speed.
[0019]
When the upper end of the lid 4 is lifted from the open state, the rod 10 is pushed against the elastic force of the compression coil spring 17. When the guide pin 20 reaches the branching portion 18b of the heart cam 18, the tip of the guide pin 20 is skewed along the right groove because the branching portion 18b has a step where the right portion is deeper. In this case, when the guide pin 20 is in the range of S of the cam groove 19, the lid 4 is not locked and can be opened and closed in accordance with the balance between the operating force and the spring force. When the rod 10 further moves and the guide pin 20 is engaged with the lock portion 18a beyond the right end of the branch portion 18b, the lid 4 is locked in the closed state.
[0020]
Next, another embodiment of the lid driving unit will be described with reference to FIGS. In this lid drive unit 22, the pinion 14 of the rotation resistance imparting damper 11 meshes with the rack gear 13 provided on the rod 10, and the rotation disk 24 is interlocked with the pinion 14 of the rotation resistance imparting damper 11 via another pinion 23. It is connected. A cam groove 25 having a heart cam 18 similar to the above is formed in the rotating disk 24 in the circumferential direction. According to this, the linear motion of the rod 10 is converted into a rotational motion and transmitted to the rotating disk 24.
[0021]
In addition, since it is the structure similar to the said linear-type lid drive unit 6 regarding provision of the bullet urging | biasing force with respect to the rod 10, and the action | operation of the heart cam 18, detailed description is omitted.
[0022]
According to this, if the ratio R / r of the radius R of the cam groove 25 and the radius r of the pinion 23 is increased, the extension of the cam groove 25 with respect to the stroke of the rod 10 becomes larger. The overstroke (s dimension in FIG. 7) of the heart cam 18 required for unlocking with respect to 10 movements, that is, the pushing amount of the lid 4 can be relatively increased.
[0023]
According to this locking mechanism, for example, if the overstroke s of the heart cam 18 is 1 mm and R / r = 2, the overstroke of the rod 10 itself can be 0.5 mm.
[0024]
When this is the linear cam groove 19 of the first embodiment, the stroke of the rod 10 required for release is the distance l from the pivot point P of the lid 4 to the connecting end (10a) of the rod 10 and the pivot point of the lid 4 Since it is determined by the ratio of the distance L from P to the point of action of the pushing force, if L / l is 2, the lid 4 must be pushed 2 mm in the first embodiment, whereas the method of the second embodiment pushes 1 mm. This means that the lock can be released with a smaller overstroke.
[0025]
【The invention's effect】
As described above in detail, according to the present invention, the lid opens so that the outer surface of the lower wall of the case (inner case) overlaps with a part of the outer wall . The amount of protrusion can be reduced and the appearance can be improved. In addition, by arranging the lid drive unit at a position adjacent to the outer surface of the lower wall of the case, a coil spring for opening the lid is disposed at the intermediate portion in the axial direction of the lid support shaft. In addition to improving the balance of the acting opening force, the overall external dimensions of the apparatus can be reduced. Therefore, according to the present invention, a great effect can be achieved in downsizing and improving the operability of the lidded article storage device.
