In this case, an oil sump 13 to be filled with viscous oil is formed integrally with the rear of the inner case, a damper shaft 14 having a control gear 15 which meshes with the drive gear 21 is fitted into the oil sump and attached to the inner case in such a way as to be parallel to the drive shaft, thus eliminating the need to increase the height of the inner case more than necessary and enabling reduction of the number of part items of the damper itself and its miniaturization because the oil sump for the viscous oil constituting a damper part is formed within the inner case.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a device for loading and unloading a small container provided on the instrument panel side of an automobile, for example.

[0002]

2. Description of the Related Art As this kind of conventional device for taking in and out, there is one shown in Japanese Utility Model Laid-Open No. 3-52257. Although not specifically shown, the conventional loading and unloading device includes an accessory case including an outer case fixed in a space on the instrument panel side and an inner case rotatably supported in the outer case. With respect to the former outer case, two racks are formed on both sides of the inner surface of the bottom wall of the former outer case, and the hook arms provided in the inner case are detachably engaged on the rear wall side. The latch means for stopping is provided.

For the latter inner case, a fixed cylinder is provided on the rear side in the width direction, and a drive shaft having two drive gears meshing with the two racks is provided in the fixed cylinder. While being rotatably fitted, a viscous oil is filled in the gap between the drive shaft and the fixed cylinder, and a torsion coil spring that constantly biases the inner case in the opening direction is attached to the outer circumference of the fixed cylinder. Has become.

Therefore, when using the accessory case equipped with such a loading / unloading device, if the front surface of the inner case, which is locked at the closed position in the outer case, is slightly pushed inward, the hook arm is locked by the latch means. Is automatically released, the spring pressure of the torsion coil spring and the rotation of each drive gear on the rack are obtained, and the inner case is automatically moved from the opening of the outer case in the opening direction. I mean,
At this time, the braking force is applied to the rotation of the drive gears provided at both ends of the drive shaft by the resistance force of the viscous oil filled in the gap between the drive shaft and the fixed cylinder.
The inner case is guaranteed to move slowly.

On the contrary, when the inner case in the open state is again moved to the closed position in the outer case, the respective drive gears are rotated in the reverse direction against the spring pressure of the torsion coil spring. When the front surface of the inner case is pressed, the hook arms of the inner case are locked by the latch means, so that the inner case is locked in the outer case.

[0006]

Therefore, under the conventional loading and unloading device, the moving speed of the inner case with respect to the opening direction can be braked without using an independent damper as in the prior art. It may appear on other devices.

However, in the conventional loading / unloading device,
When the fixed cylinder provided on the inner case side and the drive shaft fitted in the fixed cylinder are also used as the damper means, the radial dimension of the fixed cylinder naturally increases, and accordingly Since the height of the inner case itself will also become large, the above-mentioned dual-purpose structure is adversely affected, especially when a thin accessory case for storing cards, business cards, etc. is targeted. There is a big problem that thinning cannot be expected.

Further, in the specification of the conventional loading / unloading device,
Although not described in detail, at least under the configuration in which the drive shaft having the two drive gears is fitted in the fixed cylinder,
One of the drive gears must be molded separately from the drive shaft, and the separately molded gear must be fixed to the end of the drive shaft later, which inevitably complicates the assembly work. It cannot be denied that it cannot be denied that urging the opening and closing movement of the inner case by the action of the two racks and the two drive gears also complicates the device itself.

[0009]

The present invention was developed in order to effectively solve the problems of the conventional device for taking in and out, and the invention according to claim 1 opens and closes the inner case to the outer case. While being movably supported, the inner case is always urged in the opening direction by the urging spring pressure, while a rack is formed on the outer case side, and a drive shaft having a drive gear meshing with the rack is formed on the inner case side. Assuming that the accessory case is mounted and removed, an oil sump for filling viscous oil is integrally formed in the rear part of the inner case, and a damper shaft having a braking gear that meshes with the drive gear of the drive shaft is provided in the oil sump. Insert the
The damper shaft is rotatably attached to the inner case in parallel with the drive shaft.

The invention according to claim 2 is the above-mentioned claim 1.
Under the described invention, one rack is formed on one side of the outer case, and one drive gear that meshes with the rack is provided on one end side of the drive shaft, and the rack and the drive gear that are present only on the one side are provided. By the action, the structure that opens and closes the inner case is adopted.
In this case, the guide window is opened on the bottom wall of the outer case where the rack is not formed, and the sliding piece that slides along the hole edge of the guide window on the corresponding bottom wall of the inner case. It is preferable that the sliding movement of the sliding piece with respect to the hole edge of the guide window guides the opening / closing movement of the inner case.

Therefore, according to the first aspect of the present invention, the damper part and the drive part are separated from each other without adopting the conventional combined structure, so that the diameter of the damper shaft and the drive shaft is Since the diameter is as small as possible and it is not necessary to increase the height of the inner case itself, it is of course suitable for a thin accessory case for storing cards and business cards. However, due to the fact that the viscous oil reservoir that composes the damper part is integrally formed in the rear part of the inner case, it is possible to reduce the number of parts and downsize the damper as compared with the conventional independent damper. Will be able to contribute greatly.

Further, according to the second aspect of the invention, the action of one rack and one drive gear existing only on one side promotes the opening / closing movement of the inner case, so that the number of parts is also reduced. Needless to say, it is possible to fully reduce the size of the loading / unloading device itself, but especially when mounting the damper shaft and drive shaft on the inner case side, each shaft can be mounted on the inner case with one touch. Therefore, the assembling work is very simple and easy.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. Also, as shown in FIG. 1, a loading / unloading device according to the embodiment is also installed in a space on the instrument panel side. A resin-made outer case 1 to be fixed, and a resin-made inner case 1 rotatably supported in the outer case 1
It was developed for the accessory case consisting of 1.

As shown in FIG. 2, the former outer case 1 is integrally molded into a box-shaped body having an opening on the front side, and a hook arm of an inner case 11 described later is detachably engaged with the rear wall thereof. In addition to providing the latching means 2 for stopping, one rack 3 for engaging a drive gear described later is formed in the longitudinal direction on one side of the inner surface of the upper wall, while guiding the movement of the drive gear to a portion corresponding to the rack 3 on the bottom wall. The small guide window 4 is opened, the large guide window 5 is opened on the side of the bottom wall where the rack 3 is not formed, and the stopper portion 6 is formed on the side edge near the center of the large guide window 5. The elastic blade piece 7 is formed on the side edge near the opening, and the sliding piece of the inner case 11 described later is slid along the outer side edge of the large guide window 5.

As for the latter inner case 11, as shown in FIGS. 3 and 4, it is integrally molded into a tray-like body having a relatively large front plate 12, and a viscous oil is filled in the central portion of the outer surface of the rear wall. A cylindrical oil sump 13 is integrally formed, and a bearing space 16 is rotatably attached to the opening side of the oil sump 13 and a damper shaft 14 having one braking gear 15 is defined to form a tip end of the damper shaft 14. The portion 14a to the bearing space 1
When the braking gear 15 is completely pushed into the bearing space 16 while being fitted into the oil sump 13 from the lateral direction of 6, the lock claw 17 provided on the bearing space 16 side is released.
It is configured to be attached to the inner case 11 side by one-touch without engaging with the side surface of the damper shaft 14 and coming off.

In the figure, 18 is a seal washer provided on the damper shaft 14 for preventing the viscous oil from flowing out of the oil sump 13, and 19 is provided on the rear wall opposite to the bearing space 16 so as to project therefrom. It is a hook.

On the rear side of the inner case 11, as shown in the drawing, a bearing space 22 for rotatably mounting a drive shaft 20 having one drive gear 21 only at one end inside the oil sump 13 is provided. And a lock hole 24 is formed on one side wall of the bearing space 22 and a lock claw 24 is formed on the other side wall of the bearing space 22, so that one end of the drive shaft 20 is inserted into the bearing hole 23. The other end of the drive shaft 20 is elastically engaged with the other end of the drive shaft 20 by pushing the other end of the drive shaft 20 toward the lock claw 24 from above while inserting the same.
It is configured so that it can be attached to the inner case 11 side with one touch without slipping out even if 0.

In the figure, reference numeral 25 denotes a torsion coil spring which is attached to the outer periphery of the drive shaft 20 and always urges the inner case 11 in the opening direction, one end of which is fixed to the drive shaft 20 side and the other of which is fixed. The end is locked to the bottom of the bearing space 22.

Further, with respect to the outer surface of the bottom wall of the inner case 11, in particular, as shown in FIG. 4, a projecting piece 26 that collides with the stopper portion 6 of the outer case 1 and restricts the open position of the inner case 11. , The inner case 11 by elastically contacting the elastic blade piece 7
Rib wall 27 that prevents rattling in the vertical and horizontal directions of the
And the sliding piece 28 that slides along the outer side edge of the large guide window 5 are integrally formed.

Therefore, when assembling the accessory case provided with such a loading / unloading device, as described above, first, as shown in FIG. 5, the tip end portion 14a of the damper shaft 14 is removed from the lateral opening of the bearing space 16. The braking gear 1 is fitted into an oil sump 13 filled with viscous oil (not shown).
5 is completely pushed into the bearing space 16 and the braking gear 15
The lock claw 17 is engaged with the side surface of the drive shaft 20 so that the damper shaft 14 is rotatably attached to the inner case 11 side, and at the same time, one end of the drive shaft 20 is inserted into the bearing hole 23 while The drive shaft 20 is also rotatably attached to the inner case 11 side by pressing it strongly toward the lock claw 24 and engaging the lock claw 24 with the other end of the drive shaft 20.

Further, in this state, the damper shaft 14 and the drive shaft 20 are arranged in parallel in the lateral direction as shown in the drawing because the damper part and the drive part are separated from each other. Therefore, compared with the conventional one, the diameters of the damper shaft 14 and the drive shaft 20 can be made as small as possible, and the height dimension on the inner case 11 side can be reduced. This is very convenient when targeting a thin accessory case for storing cards and business cards. Both shafts 14 and 2
It goes without saying that when 0 is attached to the inner case 11 side, the braking gear 15 and the drive gear 21 automatically mesh.

Therefore, after that, the inner case 11 is replaced by the outer case 1.
If the outer case 1 is supported in an openable and closable manner inside, and is fixed in a space on the instrument panel (not shown) side,
This allows immediate use of the accessory case.

When the inner case 11 locked at the closed position in the outer case 1 is moved in the opening direction, the front plate 12 of the inner case 11 is slightly pushed inward as in the conventional case. As shown in FIG. 6, the latched state of the hook arm 19 by the latch means 2 is automatically released, so that the spring pressure of the torsion coil spring 25 and the rotation of one drive gear 21 with respect to the rack 3 are obtained. Until the projecting piece 26 described above collides with the stopper portion 6, the inner case 11 remains in the outer case 1.
However, at this time, the resistance force of the viscous oil filled in the oil sump 13 is transmitted from the braking gear 15 to the drive gear 21 of the drive shaft 20. The case 11 is guaranteed to move slowly in the opening direction.

On the contrary, when the inner case 11 in the open state is again moved to the closed position in the outer case 1, one drive gear is resisted against the biasing spring pressure of the torsion coil spring 25. When the front plate 12 of the inner case 11 is pressed while rotating 21 in the reverse direction, the hook arms 19 provided on the rear wall of the inner case 11 are locked to the latch means 2 of the outer case 1.
As a result, as shown in FIG. 7, the inner case 11 is securely locked at the closed position of the outer case 1, and there is no risk of accidentally moving in the opening direction.

Note that, under the present embodiment, in order to simplify the apparatus itself, one rack 3 is formed on one side of the outer case 1, and one drive gear 21 is provided at one end of the drive shaft 20. When the inner case 11 is opened and closed with respect to the outer case 1 by the action of the rack 3 and the drive gear 21 existing only on one side, the inner case 11 is opened and closed with respect to the outer case 1. May tilt. However, in order to prevent such a situation from occurring, the configuration in which the sliding piece 28 of the inner case 11 is slid along the outer side edge of the large guide window 5 of the outer case 1 is positively adopted. Therefore, the inner case 11 never moves obliquely, and in combination with the elastic contact state of the elastic blade piece 7 with the rib wall 27 described above, it is possible to smoothly move inside the outer case 1.

[0026]

As described above, the loading / unloading device of the present invention is
By adopting the above configuration, since it is not necessary to increase the height dimension of the inner case itself, it is, of course, particularly suitable for a thin accessory case for storing cards, business cards, etc., but of course, By forming the oil reservoir of viscous oil that constitutes the damper part integrally with the rear part of the inner case,
Compared with the one that used the independent damper,
It also contributes greatly to the reduction of the number of parts and the miniaturization of the damper itself.

It is needless to say that urging the opening and closing movement of the inner case with one rack and one drive gear present on only one side enables downsizing of the loading and unloading device itself, but in particular the damper. When the shafts and the drive shafts are attached to the inner case, the shafts can be attached to the inner case side with one touch, so that the assembling work is greatly simplified. In this case, if the sliding piece of the inner case is slid along the side edge of the guide window provided in the outer case, the smooth movement of the inner case can be ensured at the same time.
