Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to, for example, ashtrays and
This invention relates to an improvement in an opening/closing device for opening and closing storage boxes such as glove boxes.

[Conventional technology]

As a conventional opening/closing device for a storage box of this type, there is one disclosed in, for example, Japanese Patent Application Laid-Open No. 83783/1983.

As shown in FIG. 3, the conventional opening/closing device includes a housing 1 formed on an instrument panel or the like.
A storage box 2 is rotatably supported in the vertical direction via support shafts 3 protruding from both side walls of the storage box 2, and an arcuate rack gear 4 is integrally mounted on one side wall of the storage box 2. On the other hand, a rotary damper 5 using viscosity of grease or the like is provided on the outer wall of the housing 1 facing the rack gear 4, and an input gear 7 is provided at the tip of the input shaft 6 of the rotary damper 5. The input gear 7 is configured to mesh with the rack gear 4 of the storage box 2.

The input shaft 6 of the rotary damper 5 is separated into a base side and a tip side, and each end is connected by a spring 8 that performs a clutch action.

When actually opening the storage box 2, the locking means (not shown) provided between the storage box 2 and the housing 1 is released, and the storage box 2 is opened.
The storage box 2 automatically rotates downward due to its own weight and the weight of the internal contents, but the rotation of the storage box 2 is transmitted to the rotary damper 5 from the input gear 7 of the input shaft 6 that meshes with the rack gear 4. Since the rotation speed of the storage box 2 is controlled, the storage box 2 opens quietly and slowly.

Conversely, when closing the storage box 2, the storage box 2
When the storage box 2 is rotated upward by hand, the rotation of the storage box 2 is not transmitted to the rotary damper 5 due to the clutch action of the spring 8, making it possible to easily close the storage box 2 by hand. It is something.

[Problem that the invention attempts to solve]

However, in such a conventional opening/closing device, the input gear 7 is provided on the input shaft 6 side of the rotary damper 5, and the rack gear 4 is integrally formed on the storage box 2 side, so that both gears 4 and 7 are connected to each other. After obtaining the occlusal condition, storage box 2
Since a configuration is adopted in which the rotation of
There is a major problem in that the assembly work is extremely difficult in obtaining accurate occlusal positional relationships.

In addition, because the conventional opening/closing device is only applicable to the storage box 2, which rotates in the vertical direction due to its structure,
Not only is it completely unsuitable for, for example, an ashtray that moves linearly with respect to the housing 1, but the storage box 2
Since the formation position of the side rack gear 4 is also limited to the side wall surface of the storage box 2, there is also the problem that the opening/closing device itself, including the storage box 2, naturally bulges out laterally. Ta.

[Means for solving problems]

The present invention was developed in order to effectively solve the problems of the conventional opening/closing device described above, and includes a housing that movably supports a storage box, and a spring between the housing and the storage box. is used to impart a moving force to the storage box in a predetermined direction, while a friction ring provided on the input shaft of the rotary damper is brought into direct elastic contact with a desired wall surface of the storage box to control the moving speed of the storage box. We adopted a configuration that regulates the speed of the engine.

[Effect]

Therefore, in the case of this invention, conventional processing and
Without using any gears that require assembly precision, the friction ring provided on the input shaft of the rotary damper can be directly pressed into contact with the desired wall surface of the storage box that is movably supported within the housing. , the moving speed of the storage box can be easily controlled.

〔Example〕

Hereinafter, the present invention will be described in detail based on an illustrated embodiment. This embodiment is applied to a vehicle ashtray that moves linearly with respect to a housing, and specifically, as shown in FIG. As shown, an ashtray 12 serving as a storage box is supported within the housing 11 via a rail mechanism or the like so as to be linearly movable, and a compression coil-shaped spring 13 is interposed between the back wall of the housing 11 and the back wall of the ashtray 12. In addition, the ashtray 12 is configured to apply a moving force in the forward direction, and the friction ring 14 is always in resilient pressure contact with the lower wall surface of the ashtray 12.

Further, as shown in FIG. 2, the elastic pressure contact structure of the friction ring 14 includes an arm member 15 that pivots via a shaft 16 at a location facing the lower wall surface of the ashtray 12 of the housing 11, and the arm member 15 pivots through a shaft 16. While the member 15 is always urged upward via a torsion spring 17, a rotary damper 18 using viscosity of grease or the like is attached to the upper end of the arm member 15, and the input of the rotary damper 18 is By providing the friction ring 14 on the shaft 19, the friction ring 14 is brought into direct elastic pressure contact with the lower wall surface of the ashtray 12.

Furthermore, in this embodiment, when the ashtray 12 moves forward, the friction ring 14 comes into strong elastic pressure contact with the lower wall surface of the ashtray 12, and when the ashtray moves backward, the arm member 15 is arranged so that the elastic contact becomes weaker. The fulcrum is set on the right side of the figure.

Although not specifically shown, it goes without saying that a locking means is provided for locking the ashtray 12 against at least the spring pressure of the spring 13 when the ashtray 12 is sunk into the housing 11. stomach.

Therefore, using the opening/closing device with such a configuration, the ashtray 1
When opening the ashtray 12, hold the front plate 12a of the ashtray 12 and pull it out until the locking means is unlocked.
The forward movement of the ashtray 12 is transmitted to the rotary damper 18 via the friction ring 14 which is in elastic contact with the lower wall surface of the ashtray 12, and the ashtray 12 Since the forward speed of the ashtray 12 is controlled, the ashtray 12 moves forward quietly and slowly.

In view of this, in order to more effectively control the forward speed of the ashtray 12, it is preferable to provide the lower wall surface of the ashtray 12, which contacts the friction ring 14, with a fine uneven shape that increases frictional resistance.

Conversely, when closing the ashtray 12, the ashtray 12 can be easily sunk into the housing 11 by pushing in the front plate 12a of the ashtray 12 and moving the ashtray 12 back into the housing 11. becomes.

Particularly in this case, since the ashtray 12 moves backward while pushing down the friction ring 14 by the lower wall surface of the ashtray 12, the regulating action of the rotary damper 18 no longer works, and the ashtray 12 This will allow you to retreat smoothly.

In the above embodiment, the friction ring 14 provided on the input shaft 19 of the rotary damper 18 is in elastic contact with the lower wall surface of the ashtray 12, but the present invention is not limited to this. Friction ring 14 as ashtray 1
It goes without saying that a similar speed regulating effect can be obtained even if it is in elastic contact with the side wall surface, etc. of No. 2.

Furthermore, the above embodiment has a linearly moving vehicle ashtray 1.
2, but it can also be applied to a storage box that rotates in the vertical direction by using the spring pressure of a spring, by bringing the friction ring 14 into elastic contact with the side wall surface of the storage box. Based on this principle, a regulating effect on the moving speed of the storage box can be obtained.

"Effect of the invention" As described above, the present invention movably supports the storage box within the housing, and also provides a force for moving the storage box in a predetermined direction by interposing a spring between the housing and the storage box. On the other hand, since the system is characterized in that the moving speed of the storage box is adjusted by bringing a friction ring provided on the input shaft of the rotary damper into elastic contact with the desired wall surface of the storage box, conventional processing and assembly are not required. Even without using gears that require high attachment accuracy,
The moving speed of the storage box can be easily controlled by simply bringing the friction ring provided on the input shaft of the rotary damper into direct elastic contact with the desired wall surface of the storage box movably supported within the housing.

Moreover, this invention can also be applied to storage boxes that move linearly, which was considered completely impossible with conventional opening/closing devices.
It has the advantage of being practical and applicable.
