BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a drawer for a vehicle having a so-called push-open function.

[0002]

2. Description of the Related Art A conventional drawer of this type has some structural differences, but basically has at least a housing fixed to a vehicle body side and a drawer supported so as to be able to be pulled out into the housing. A body, biasing means for constantly urging the drawer body out of the housing, and releasable locking means for locking the drawer body in the housing against the urging force of the urging means. As the locking means, a heart-shaped cam member having a cam groove is generally used.

That is, under a drawer using a heart-shaped cam member as a locking means, the cam member is pivotally mounted on the housing side with spring pressure interposed therebetween, while the cam member is mounted on the rear end side of the drawer body. If a pin member that engages with and disengages from the cam groove of the cam member is provided and the drawer locked in the housing is slightly pushed into the housing, the locking of the pin member in the cam groove is released, and the lock of the cam member is released. This allows the drawer to move automatically from the inside of the housing to the opening direction by the urging force of the urging means, thereby ensuring the open state. Conversely, the drawer is moved inside the housing. In conjunction with this, in conjunction with this, the pin member is locked in the cam groove while rotating the cam member in a predetermined direction, and the drawer is locked in the housing against the urging force of the urging means. , Its closed state And thus it can be guaranteed.

However, the use of such a cam member as a locking means is that when the drawer is locked, the drawer moves in the opening direction when a large inertia force is applied during a collision of an automobile, sudden braking, or the like. In the same manner as in the case where the pull-out member is moved in the same direction as the direction of the inertial force, the pin member is automatically disengaged from the cam groove, and the turning of the cam member in the unlocking direction is permitted. In addition, there is a possibility that the drawer may accidentally project outward from the inside of the housing.

In order to prevent such a situation from occurring, for example, as disclosed in Japanese Utility Model Laid-Open No. 25332/1990,
A guide piece is integrally extended on the rear end side of the cam member, a heavy inertial response body is slidably disposed on the guide piece, and the inertial response body is moved to the rear end of the cam member by a tension spring. It is necessary to provide a safety function in which a lock cylinder is provided in a corresponding portion of the housing to allow the end of the inertial responsive element to enter while being urged in the part direction.

[0006]

However, the provision of such a safety function not only requires an extra inertial response body besides the heart-shaped cam member and the pin member but also a separate inertial response body, and the rear of the cam member. A guide piece is integrally extended on the end side, and an inertia responsive element is disposed on the guide piece via the pulling force of a tension spring, or a lock cylinder body that allows the end of the inertia responsive element to enter the housing. Since the parts must be formed separately, the number of parts naturally increases, and not only the drawer itself becomes costly or bulky, but also the assembly man-hours increase, There is a problem that workability is also deteriorated. Accordingly, there is a need in the art to reconsider the use of a heart-shaped cam member for the locking means, which must provide a safety function.

[0007]

Means for Solving the Problems The present invention has been developed in order to effectively solve such a conventional problem, and includes a housing fixed to a vehicle body side and a drawer supported in the housing. A drawer, biasing means for constantly biasing the drawer outward of the housing, and
A releasable lock that locks into the housing against the forces
Given the automotive drawing device and a click means, the
The locking means is a case fixed to the opening edge side of the housing.

The lock pawl of the lock means on the front end side of the drawer.
A configuration that locks to the locked locking portion is adopted.

[0008]

Therefore, in the present invention, the drawer can be automatically locked in the housing only by locking the lock claw on the housing side to the locking portion on the drawer body via spring pressure. In addition, the drawer can be automatically moved out of the housing by the urging force of the urging means simply by moving the lock claw in the reverse direction with the push knob. In this state, even if a large inertial force is received, the locking of the lock claw with the locking portion can reliably prevent the drawer from moving with the inertial force. Thus, there is no need to separately provide a safety function.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to an embodiment shown in the drawings. The drawer according to the embodiment is applied to an automobile cup holder device having a push-open function. As shown in FIGS. 1 and 2, a housing 1 fixed to an instrument panel side of a vehicle body, a holder body 2 supported so as to be able to be pulled out into the housing 1 and a holder body A pair of torsion coil springs 3 for constantly biasing the housing 2 to the outside of the housing 1, and locking means for locking the holder body 2 in the housing 1 against the biasing spring pressure of each of the torsion coil springs 3. However, the feature is that the following configuration is adopted.

That is, the entire housing 1 is formed to have an inverted U-shaped cross section, and guide rails 4 for guiding the advance / retreat of the holder main body 2 are provided on the inner surfaces of both side walls, while the upper wall and both side walls are formed. A plurality of locking claws 5 are provided near the opening to elastically lock the edge of the mounting space defined on the instrument panel side, and at the center of the rear end wall at the back of the mounting space. The projecting legs 6 to be fitted into the established fixing holes are integrally extended, and holes 7a or notches 7 are formed on both side edges of the opening.
b, a fitting state of the projection leg 6 into the fixing hole is obtained, and each locking claw 5 is locked to the edge of the mounting cavity, and at the same time, the hole 7a or the notch of the flange 7 is cut out. The housing 1 can be easily and securely fixed in the mounting space by simply fitting a projection provided on the same edge side in the portion 7b, and the engaging claws 8a are provided on both side walls.
Are separately formed, and the rising pieces 10 on both sides of the metal bottom plate 9 are applied between the respective step parts 8 so as to form the respective rising pieces 1.
The bottom plate 9 can be easily attached to the bottom side of the housing 1 by engaging the engaging claw 8a into the 0 notch hole 10a.

Also, for the inner surface of the upper wall of the housing 1,
In particular, as is clear from FIG.
And a regulating wall 11 against which the stopper claw contacts
A long rack 12 is formed from the center of the regulating wall 11 to the center of the rear wall, and a pair of slide grooves 13 having an arc shape are formed on both sides of the rear end of the upper wall. A head 14a of a piece member 14 to which the main body 3a of the torsion coil spring 3 is attached is movably fitted in the frame 13. The body 3a of the torsion coil spring 3 is formed into an open coil shape having a constant pitch, and is mounted on the shaft portion 14b of the piece member 14 in a compressed state by the action of the pressing claw 15; , Its both ends 3b
On each side, one end is fixed to the rear wall of the housing 1, and the other end is fixed to the rear end of the holder body 2.

In this embodiment, in addition to the above configuration, the mounting recess 16 is formed at the center of the front end of the housing 1.
Are integrally formed, and the following locking means is provided in the mounting recess 16. The locking means is, as shown in FIG. 3, a case 17 fixed via a locking claw 17a in the mounting recess 16 of the housing 1.
A push knob 18 movably supported in the case 17 and a lock claw 19 disposed in the case 17 and constantly urged downward by the spring pressure of the compression coil spring 20. Defines a holding space 21 at the front end side for holding the lock claw 19 in a vertically movable manner, and a holding hole 22 for individually guiding the bifurcated leg piece 18a of the push knob 18 at the rear end side. The knob 18 has its own forked leg piece 18.
A guide groove 23 which is notched in an inclined manner is individually formed on each upper surface side of the upper surface a, and the lock claw 19 forms an attachment hole portion 19a for the compression coil spring 20 on the upper surface side, and the above-described respective guide grooves 23 A pair of arms 24 having a substantially rhombic cross-section that slides inside 23 is formed.

Therefore, when assembling such a lock means, the fork-shaped leg piece 18a of the push knob 18 is pressed together with the compression coil spring 20 while pressing the lock claw 19 into the holding space 21. Forcibly insert the lock claw 19 into the corresponding holding hole 22 from the
4 automatically fits into the corresponding guide groove 23,
The push knob 18 and the lock claw 19 are simultaneously
It will be easily assembled inside. In a normal state, as shown in FIG. 4A, the tip of the lock claw 19 projects downward from the holding space 21 by the spring pressure of the compression coil spring 20, but the push knob 18 is inserted into the case 17. When pushed in, as shown in FIG. 4B, the arm portion 24 of the lock claw 19 is pushed against the guide groove 2 of the push knob 18 against the spring pressure.
When the push-in operation is released, the lock claw 19 is automatically lowered again by the spring pressure of the compression coil spring 20, and the push knob 18 is also moved outward by a predetermined amount. It will be pushed out.

On the other hand, the holder body 2 is provided with a pair of cup holes 25 for inserting a cup at the front end thereof, and a pair of stopper claws 26 abutting on the regulating wall 11 on both sides of the rear end. An oil damper 27 having a braking gear 27a engaging with the rack 12 is provided at the center of the end in a fitting manner, and a locking recess 28 for locking the tip of the lock claw 19 is provided at the center of the front end. A concave groove 29 allowing the movement of the lock claw 19 from the locking concave portion 28 is formed continuously. Two projections 30 which are slidably fitted on the guide rails 4 are formed on both side edges of the rear end thereof at a predetermined interval, and are formed between the projections 30 on the corresponding surfaces of the guide rails 4. The elastic wall 30a which makes elastic contact is provided.

Therefore, when assembling the cup holder having such a configuration, first, a pair of torsion coil springs 3 are assembled via the bridge member 14 to the housing 1 side.
The holder main body 2 is supported in the housing 1. In particular, when the torsion coil spring 3 is mounted on the bridge member 14, the main body 3a is connected to the shaft 1 of the bridge member 14.
The main body 3a is simply and securely mounted on the shaft portion 14b of the piece member 14 in a compressed state by the action of the holding claw 15 simply by fitting the holding claw 15 into the 4b while obtaining the bending of the holding claw 15. In other words, there is no fear that the torsion coil spring 3 will inadvertently rattle under the compression mounting.

Also, the holder body 2 is provided inside with the bottom plate 9.
5 and 6, when the housing 1 supporting the housing 1 is fixed to the instrument panel side, the projecting legs 6 are fitted into the fixing holes 31 and the locking claws 5 are attached to the mounting cavities as shown in FIGS. Of the flange 7
The housing 1 can be easily and reliably fixed simply by fitting the convex portion 33 provided in advance on the same edge portion 32 side into the hole 7a or the notch portion 7b. The cup holder device can be mounted on its own or fixed to the instrument panel.
Since all the operations can be performed by one-touch operation without using an accessory part such as a screw member, it is possible to greatly contribute to improvement of workability.

At the time of actual use, the push knob 18 is pushed into the case 17 and
9 is moved upward against the spring pressure of the compression coil spring 20 to release the locking of the locking claw 19 with the locking concave portion 28. As shown in FIG.
1, the holder body 2 is automatically and slowly moved out of the housing 1 by the biasing spring pressure of the torsion coil spring 3 under the braking force of the oil damper 27. The use condition of using a part of the parts as a cup bottom receiver can be guaranteed.
In the process of moving the holder body 2, the lock claws 19
Of the lock claw 19 receiving the spring pressure of the compression coil spring 20 does not hinder at all.

Further, when the holder body 2 moves outside the housing 1, under this embodiment, as shown in the figure, a pair of torsion coil springs 3 are in a state in which the holder body 2 is left and right even. And a balanced biasing spring pressure is always applied to the holder body 2, so that the holder body 2 moves during
Not only does the holder body 2 tilt in the housing 1 and the smooth movement state cannot be ensured, but also the elastic body 30a between the projections 30 elastically contacts the guide rail 4 of the holder body 2. Since sticking can also be effectively prevented, smooth movement is also guaranteed from this point. Further, in the present embodiment, the movable mounting of the torsion coil spring 3 on the housing 1 side through the bridge member 14 is equivalent to the overall size as compared with the case where a compression coil spring or the like is used as the urging means. Has the advantage that a large biasing stroke can be obtained.

Also in the present embodiment, if the holder main body 2 is pushed into the housing 1 against the urging spring pressure of the torsion coil spring 3, the lock claw 19 is again pressed by the spring pressure of the compression coil spring 20. And the locking recess 28 on the holder body 2 side
And the holder body 2 is locked in the housing 1. In such a locked state, for example, at the time of a collision of an automobile or a sudden braking, etc., a large inertia force is applied. Also, since the lock claw 19 is securely locked in the locking recess 28 and the locked state is never released, there is no fear that the holder main body 2 is erroneously protruded outward, and also the cam member Thus, there is no need to additionally provide a safety function as in the case of using a.

In the above-described embodiment, the present invention is directed to a cup holder device. However, the present invention is not limited to this, and other devices such as an ashtray device and an accessory storage device may be used. Needless to say, the present invention can be easily applied to various kinds of automobile drawers having a push-open function.

[0021]

As described above, according to the present invention, the drawer can be locked in the housing against the urging force by adopting the above-described configuration, but in particular, in the locked state of the drawer, Even if a large inertial force is received, the locking member is firmly locked to the locking portion, so that the drawer body can be reliably prevented from moving by the inertial force, so that a conventional safety function is inevitably provided. There is no need to use a heart-shaped cam member for the locking means. Therefore, under the drawer of the present invention, not only does the number of parts increase, and the apparatus itself does not have to be increased in cost or size, but also the assembling workability is extremely good. Also, push
