Description

[Technical Field] The present invention relates to a vehicle housing device, and more particularly, in a vehicle housing device of an auto-projection type, the holding portion length of the housing at the time of projecting is reduced to improve the usability. The present invention relates to an improved structure of a projecting drive which can advantageously achieve an improvement or a reduction in storage space.

(Prior Art) A storage device for a vehicle, for example, an ashtray device incorporated in a vehicle instrument panel or the like is usually a retainer that is fixedly mounted on the vehicle body side, and a storage device that is retained in the retainer so as to be removable. The ashtray case has an ashtray case, and the ashtray case can be opened and closed by sliding the ashtray case with respect to the retainer. There is known a so-called automatic protrusion type structure in which the ashtray case is automatically protruded from the storage position to the protrusion position by means.

However, in such an automatic projecting type vehicle storage device, conventionally, as a biasing means thereof, generally, a torsion coil spring, a compression coil spring, or the like has one end on the storage body side and the other end on the retainer side. Since each of them is locked and used, a deformation allowance space of the coil spring is required between the storage body and the retainer, which causes a problem that a large space is required for mounting the device. . And, in particular, as seen in the instrument panel of a vehicle, as a vehicle component in which a large number of component units are incorporated, its large mounting space reduces the degree of freedom in designing other components. Therefore, it is not preferable.

Therefore, the applicant of the present application previously found that
In Japanese Laid-Open Patent Publication No. 61-81244 and Japanese Patent Laid-Open No. 61-81244, one of the housing and the member on the vehicle body side including the retainer is
A rack provided with engaging teeth extending in the direction of taking in and out the storage body is provided, and a pinion that meshes with the rack is provided on the other side, and a spiral spring that stores a biasing force according to the rotation of the pinion is arranged in the hollow portion of the pinion. , The urging force that is stored when the storage body is pushed against the spiral spring,
A storage device for a vehicle having a structure in which a storage device in a stored state is actuated by projecting the storage device through a pinion mechanism has been clarified.

(Problem) However, in the storage device having such a structure, in general, the pinion is formed in a disk-like shape that forms a shallow container shape, and the spiral spring is stored in the inside thereof, Since the part is locked to the pinion and the other end is locked to the fixed side member and arranged around the rotary shaft, the overall size of the device can be reduced, but the pinion itself has a large diameter. Will be realized,
Further, in such a pinion, in general, in order to exert a certain urging force in the projecting direction even on the storage body in the projecting state, the spiral spring is provided even before the rack is rotated by meshing. In order to store a certain amount of biasing force (energy), a stopper mechanism that blocks the rotation of the spiral spring at one rotation position is provided, and the stopper mechanism prevents further rotation by the biasing force of the spiral spring. Since the pinion is allowed to be reciprocally rotated by a little less than one rotation, the pinion is accommodated at least in the retracted state. It is necessary to set the outer peripheral length equal to or larger than the amount of protrusion of the body, and this also unavoidably increases the diameter of the pinion.

Further, here, the meshing position of the pinion with respect to the rack at the protruding position of the storage body is usually set rearward from the front edge of the retainer by at least the radius of the pinion or more in view of the storage space of the pinion. Therefore, in order to secure the meshing of the pinion with the rack at the projecting position of the storage body by increasing the diameter of the pinion, the pinion is kept in the retainer even under the projecting state. It was necessary to increase the length of the holding portion of the storage body located in the storage state.

Therefore, for example, in an ashtray case or the like, since the protruding amount of the container in the protruding state is small and the opening amount is small, it is difficult to say that the usability is good. There was an inherent problem that the device could not be sufficiently miniaturized because the unnecessary holding portion became large.

(Solution) Here, the present invention has been made in view of the above circumstances, and is characterized by the automatic projecting type vehicle container device as described above. a)
A retainer attached to the vehicle body side, (b) a storage body that is held in the retainer so as to be able to be taken in and out, and (c) provided on any one of a vehicle body side member including the storage body and the retainer, A rack provided with engaging teeth continuously extending in the direction of inserting and removing the storage body, and (d) a body side member including the storage body and the retainer, which are provided on the other side and mesh with the rack. By doing so, a pinion with a small diameter that can be rotated according to taking in and out of the storage body,
(E) A drive pinion having a diameter larger than that of the pinion, which is engaged with the pinion and is rotated at the same time, and a rotation of the drive pinion, which is arranged around the rotation shaft in a state of being housed in the drive pinion. And (f) a releasable lock that locks the storage body at the storage position against the biasing force of the biasing mechanism, which includes a spiral spring that stores a biasing force in the reverse rotation direction. And the mechanism.

(Embodiment) Hereinafter, in order to more specifically clarify the present invention, one embodiment of the present invention will be described in detail with reference to the drawings. In addition, in the present embodiment, an example in which the present invention is applied to an ashtray device for a vehicle as a vehicle storage device will be described.

First, FIG. 1 shows a general view of an ashtray device having a structure according to the present invention. In this figure, 10 is
The retainer is fixed to an instrument panel of a vehicle and holds the ashtray case 12. This retainer 10
Is an upper member 14 and a lower member 1 formed by bending a steel plate.
6 and 6 and are formed by spot-welding and integrating them on both side wall portions. In the present embodiment, the cigarette lighter retainer 18 is integrally attached to the upper member 14 that constitutes the retainer 10 of the ashtray device, and the front panel 20 of the ashtray device is the cigarette lighter panel. The ashtray device and the cigarette lighter are unitized by being integrated with.

Further, in the retainer 10, guide rails 22 and 22 made of synthetic resin having guide grooves extending in the front-rear direction are provided in parallel with each other on inner surfaces of both side wall portions of the retainer 10. There is.

On the other hand, the ashtray case 12 is made of a fire-resistant resin, and the ridges 24, 24 formed on both sides thereof are slidably fitted to the guide rails 22, 22 of the retainer 10. By doing so, the action of the projections 24, 24 and the guide rails 22, 22 guides the ashtray case 12 in the pulling-out direction and the storing direction. In addition, a protector 26 for fire protection is rotatably attached to the ashtray case 12 at the rear part of the container, as usual, and is biased upward by a spring (not shown).
The contact portion 28 formed on the upper surface of the retainer 6 is
By contacting a protector guide (not shown) fixedly attached to the inner surface of the upper wall of the ashtray case 1
The projecting end position of 2 is defined.

Further, as shown in FIG. 2, the ashtray case 12 is provided with a pair of engaging teeth on the side surface at the central portion of the bottom surface thereof, the engaging teeth extending continuously in the direction of inserting and removing the ashtray case 12. Rack 30 is integrally provided.

On the other hand, in the retainer 10, as shown in FIG. 3, when the ashtray case 12 is inserted into the inner surface of the bottom wall of the lower member 16, a wide rack for accommodating the rack 30 thereof is accommodated. The groove 31 is formed and the groove 31 is formed.
A through hole 32 is formed at the front edge of the concave groove 31.
A pinion 34 having a reduced diameter is provided so as to project inward. Then, when the ashtray case 12 is inserted into the retainer 10, as shown in FIG. 4, the pinion 34 is engaged with the engaging teeth of the rack 30 provided in the ashtray case 12. It is designed so that they can be engaged.

Here, the pinion 34 is shown in FIGS.
As shown in the figure, while being accommodated in a shallow container-shaped housing 36 mounted on the outer surface of the bottom wall portion of the retainer 10, it is rotated by a support shaft 38 formed to project from the bottom portion of the housing 36. It is provided by being supported as much as possible.

Further, the housing 4 has a damper 4 inside.
0 is fixedly installed, and the damper shaft 4 of the damper 40
2, the drive pinion 44 having a large diameter is attached to the rack 3
The pinion 34, which meshes with the 0 engaging tooth, is supported so as not to rotate relative to the pinion 34. This damper 4
As disclosed in Japanese Patent Application Laid-Open No. 59-179430 by the applicant of the present invention, 0 indicates that a viscous fluid is enclosed in the inside of the viscous fluid, and a blade portion integrally formed with the damper shaft 42 is included in the viscous fluid. By being rotated, the resistance of the viscous fluid can be exerted as a rotational resistance force on the damper shaft 42, and further on the drive pinion 44 supported by the damper shaft 42. .

Furthermore, the drive pinion 44 supported by the damper shaft 42 is formed as a disc-shaped member having a larger outer diameter than the pinion 34 and forming a shallow container shape, and a spiral spring 46 is provided inside thereof. It is housed around the damper 40. The outer edge of the spiral spring 46 is locked to the inner surface of the drive pinion 44, while the inner edge is locked to the outer peripheral wall of the damper 40. The drive pinion 44 is used for the spiral spring 4
When the coil spring 6 is rotated in the winding direction 6, the spiral spring 46 is wound up, and biasing force (energy) is stored in the reverse rotation direction with respect to the spiral spring 46.
Further, as is apparent from this, in this embodiment, the drive pinion 44 and the spiral spring 46 constitute an urging mechanism.

By the way, the drive pinion 44 is installed in the housing 36.
By engaging a not-shown locking piece projectingly formed on the bottom surface of the drive pinion 44 with a stopper portion 45 projectingly formed on the bottom surface of the drive pinion, its rotation is blocked at one rotation position, Only a little less than one rotation of the reciprocating rotary motion is allowed, and the rotation of the drive pinion 44 is prevented by the engagement of the locking piece with the stopper portion 45, so that the drive pinion 44 is prevented from rotating inside. The spiral spring 46 is accommodated and arranged in a state in which it is wound by a predetermined amount and stores a certain amount of biasing force. That is, as is apparent from this, the drive pinion 44 has an outer peripheral length that is at least longer than the protruding amount of the ashtray case 12, and is larger than the engaging teeth formed on the rack 30 of the ashtray case 12. The ashtray case 12 can be driven from the storage position to the projecting position via the pinion 34 by a rotational movement of a little less than one turn based on the biasing force of the spiral spring 46. The urging force in the protruding direction can still be effectively applied to the ashtray case 12 in the protruding state.

The housing 36 in which the pinion 34, the drive pinion 44, and the spiral spring 46 are housed in this way is locked to the outer surface of the bottom portion of the lower member 16 constituting the retainer 10 by a locking piece 48 thereof. Further, the pinion 34 is attached in a state of penetrating the through hole 32 and projecting into the concave groove 31 as described above by being fixed by the bolt 52 at the ear portion 50.

That is, in such an ashtray device, when the ashtray case 12 is pushed into the retainer 10,
The pinion 34 provided on the retainer 10 side with respect to the engaging teeth of the rack 30 formed on the bottom surface of the ashtray case 12.
Are engaged with each other, and the pinion 34 is rotated, so that the drive pinion 44 engaged with the pinion 34 is accommodated inside the spiral spring 4
6 is rotated in the direction in which the urging force is stored. Then, when the ashtray case 12 is pushed into the retainer 10 by this, the biasing force of the spiral spring 46 is exerted on the rack 30 via the drive pinion 44 and the pinion 34, whereby the ashtray case 12 is It will be urged in the protruding direction.

Further, here, in such an ashtray device, when the ashtray case 12 is pushed into the retainer 10, a biasing force in the protruding direction is always exerted on the ashtray case 12. In this embodiment, a locking mechanism for holding the ashtray case 12 in the stored state with respect to the retainer 10 is provided against the biasing force.
The locking mechanism includes a locking tool 60 including a locking pin 58 protruding from the bottom wall of the retainer 10 into the retainer 10.
And a cam forming a groove-shaped cam surface integrally formed on the bottom rear surface of the ashtray case 12 on the side where the engaging teeth of the rack 30 are not formed and to which the locking pin 58 is engaged and guided. And part 56.

More specifically, as shown in FIG. 6, the locking tool 60 is formed in a generally long plate shape as a whole, and the locking pin 58 is implanted at the tip portion 62 thereof. On the other hand, a sliding contact portion 66 is integrally provided on the base end portion 64. The locking tool 60 is arranged such that the locking pin 58 projects into the retainer 10 through a through hole 70 formed in the groove 31 in the bottom wall of the retainer 10 with a predetermined width. Edge 6
In FIG. 4, the bolts 72 are attached to the back surface of the retainer 10. In addition, in such an attached state, the sliding contact portion 66 is brought into contact with the back surface of the retainer 10, whereby the locking member 60 is provided with sliding resistance due to the sliding contact portion 66. Below, bolt 7
It is possible to rotate within a regulation angle by the through hole 70 with a certain rotation resistance with the rotation center at 2.

On the other hand, as shown in FIG. 7, the cam portion 56 has a substantially U-shaped outer peripheral wall portion 7 whose inner peripheral surface is a cam surface.
4 and a central projecting portion 76 projectingly formed in the central portion surrounded by the outer peripheral wall portion 74 and having an outer peripheral surface serving as a cam surface. 7
6, the engaging pin 58 of the engaging member 60 is sequentially guided in one direction according to the movement of the ashtray case 12 in the front-rear direction with respect to the retainer 10. One closed path is formed.

That is, in such a locking mechanism, when the ashtray case 12 moves in the front-rear direction, the locking tool 60 is rotated by the contact of the locking pin 58 with the cam portion 56. Therefore, the locking pin 58 is applied.
However, the locking position and the non-locking position with respect to the cam portion 56 are sequentially set. Specifically, as shown in FIG. 7, by pushing in the ashtray case 12, the locking tool 60 located at an arbitrary rotation position: a within the range regulated by the through hole 70 is shown. When the locking pin 58 is guided into the groove of the cam portion 56 and the ashtray case 12 is pushed to the pushing end, it is located at the innermost part: b, and from this state, the ashtray case 12 is pushed. By releasing the pushing force, the spiral spring 4
As the ashtray case 12 moves forward (in the opening direction) according to the urging force of 6, the locking pin 58 is guided to the locking position c of the central projection 76 of the cam portion 56, and is engaged at that position. As a result, the ashtray case 12 is prevented from moving forward, and the ashtray case 12 is locked in its closed position. On the other hand, if the ashtray case 12 is pushed in again from this closed position,
The locking pin 58 is the innermost part in the groove part of the cam part 56: d
Then, the ashtray case 12 is allowed to move forward again again, and the locking pin 58 is locked by the cam portion 56.
From the inside of the groove portion, it is to be detached in the e direction.

Therefore, in the ashtray device having the above structure,
When the ashtray case 12 is pushed into the retainer 10 from its open position, the drive pinion 44 rotates in the direction in which the spiral spring 46 is wound according to the rearward movement of the ashtray case 12 and the engagement between the rack 30 and the pinion 34. As a result, a biasing force for rotating the pinion 34 in the opposite direction is stored in the spiral spring 46, and when the ashtray case 12 is pushed to a position close to the closed position, the engaging mechanism that constitutes the locking mechanism is formed. When the stop pin 58 engages with the cam portion 56 and then the pushing force is released, the ashtray case 12 becomes
By the engagement of the engagement pin 58 with the cam portion 56, the closed state is maintained. On the other hand, by pushing the ashtray case 12 slightly backward from the closed state, the locking of the locking mechanism is released, and the urging force of the spiral spring 46 is transferred from the drive pinion 44 to the pinion 34. The ashtray case 12 which is extended to the rack 30
However, under the speed control of the damper 40, the contact portion 28 of the protector 26 is automatically protruded to the open restriction state up to the projection restriction end position.

Since the pinion 34 meshed with the rack 30 of the ashtray case 12 does not have a biasing mechanism itself, the pinion 34 is formed with a sufficiently small outer diameter without impairing its driving force transmitting function. Therefore, by reducing the diameter of the pinion 34 and arranging the pinion 34 at the front end of the retainer 10, the distance of the meshing position with respect to the rack 30 from the front end of the retainer 10 can be increased. It can be set small. Thus, in the protruding state of the ashtray case 12, it is possible to extremely advantageously reduce the length (1 in FIG. 4) of the holding portion of the ashtray case 12 which is located in the retainer 10 in the housed state. In addition, since a large opening amount can be advantageously obtained under the protruding state,
It has excellent usability.

Further, in such an ashtray device, a drive pinion 44 having a spiral spring 46 that stores a biasing force according to the rotation is used as a biasing mechanism that exerts a rotary driving force on the pinion 34. Therefore, the device can be advantageously made compact, and the effects of reducing the mounting space and ensuring the degree of design freedom can be effectively exhibited.

Further, in the ashtray device according to the present embodiment, the damper 40 causes the ashtray case 12 to project slowly, so that the sense of quality is improved.
Further, it is possible to effectively prevent the scattering of the butts and the like due to the sudden projecting operation.

Next, another specific example of the biasing mechanism that can be suitably used in the vehicle ashtray device as described above is shown in FIG. In this specific example, members having the same structure as the urging mechanism adopted in the above embodiment are designated by the same reference numerals in the drawings,
Detailed description thereof will be omitted.

That is, in the urging mechanism of this embodiment, the drive pinion 44 is attached to the support shaft 80 provided in the housing 36, and the drive pinion 4 is provided.
By rotating 4 the urging force in the reverse rotation direction is stored in the spiral spring 46 housed and arranged inside. Further, the housing 36 is provided with the pinion 34 in a state in which the pinion 34 is engaged with the drive pinion 44 and simultaneously rotated by being supported by the support shaft 82, and the urging force of the spiral spring 46 is The drive force can be exerted on the pinion 34 as a rotational drive force via the drive pinion 44.

Although such a biasing mechanism is not shown,
Similar to the above embodiment, the pinion 34 is attached to the retainer (10) in a state of being meshed with the rack (30) of the ashtray case (12) inserted into the retainer (10). .

In the urging mechanism of this embodiment, unlike the previous example, the damper 40 is provided at the portion of the housing 36 where the pinion 34 is arranged, and the damper shaft of the damper 40 causes the pinion 34 to move. A support shaft 82 to be attached is configured, and the pinion 34 is attached to the support shaft 82 such that the pinion 34 cannot rotate relative to the support shaft 82.
Then, the rotational driving force of the spiral spring 46 transmitted via the drive pinion 44 and the rotational resistance force of the damper 40 are directly applied to the pinion 34, respectively.
Thus, the pinion 34 can be driven to rotate under the speed control of the damper 40 based on the biasing force of the spiral spring 46.

Therefore, even in the urging mechanism having such a structure,
It has the same function as that of the above-mentioned embodiment, and by using such a biasing mechanism, the same effects as those of the above-mentioned embodiment can be effectively exhibited.

Further, in the urging mechanism according to the present embodiment, since it is not necessary to secure the installation space of the damper 40 inside the drive pinion 44, it is possible to reduce the size of the drive pinion 44 and the urging mechanism. This can be advantageously achieved, and thus has an advantage that space saving of the ashtray device can be achieved.

Although the embodiments of the present invention have been described in detail above, this is a literal example, and the present invention should not be construed as being limited to such specific examples.

For example, although the rack 30 is integrally formed with the ashtray case 12 in the above-described embodiment, the rack 30 is
While the retainer 10 or the vehicle body side fixing member side is provided,
It is also possible to arrange the pinion 34 and the drive pinion 44 which are meshed with the rack 30 on the ashtray case 12 side.

Further, the locking mechanism applied to the present invention is not limited to the structure as in the above-described embodiment, and may be, for example, one including a rotatable cam piece and a fixed locking pin, or a cam. Any known mechanism such as a simple locking mechanism that is unlocked by a lever operation or the like without a mechanism can be adopted.

In addition, in the above embodiment, an example in which the present invention is applied to a sliding type ashtray device has been shown, but the present invention can be well applied to other various container devices,
As a result, the effect of the present invention such as reduction of the holding length in the protruding state can be effectively exhibited, and, for example, the present invention can be applied to the operation switch panel in which the operation switch panel is projected from the storage position. When applied to a device or a pull-out type cup holder, the holding length in the projecting state can be shortened to reduce the size of the container, and thus the device can be made more compact. That will be the case.

In addition, although not listed one by one, the present invention can be implemented in a mode in which various changes, modifications, improvements, etc. are added based on the knowledge of those skilled in the art, and such an embodiment has the gist of the present invention. It goes without saying that all are included within the scope of the present invention unless deviated.

(Effect of the Invention) As is apparent from the above description, in the vehicle accommodating device having the structure according to the present invention, the pinion that engages with the rack is engaged separately from the pinion that engages directly with the rack. Then, since the drive pinion that exerts the rotational drive force on the pinion is provided by the biasing force of the spiral spring arranged inside the pinion, it is advantageous to reduce the diameter of the pinion without impairing its function. Therefore, by setting the meshing position of the pinion with respect to the rack at the protruding position of the storage body in the vicinity of the front end edge of the retainer, the holding amount of the storage body in the protruding state can be reduced. Therefore, it is possible to improve the usability of the storage device or reduce the storage space.
