Abstract

PROBLEM TO BE SOLVED: To provide a lid opening and closing device in a console box. SOLUTION: In this lid opening and closing device in the console box, the lid L is rotatably fitted to an opening part of a console box body B through a hinge shaft 1 and a hinge arm 6, and the lid L is always energized in the opening direction with energizing spring pressure. The lid opening and closing device includes a rotary damper 4 having a braking gear 4a, and the hinge shaft 1 side is provided with a fan-shaped gear 5 meshing the braking gear 4a of the rotary damper 4, and the hinge arm 6 side is provided with a pressing part 6a for rotating the fan-shaped gear 5 in the course of opening the lid L, whereby according to opening of the lid L, the fan-shaped gear 5 is rotated by the pressing part 6a so that the braking force of the rotary damper 4 is transmitted to the lid L. Thus, the lid L can be effectively prevented from being loosened by energizing spring pressure at the fully open position.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid opening and closing device for a console box of an automobile.

[0002]

2. Description of the Related Art A console box is arranged between a driver's seat and a passenger's seat of a car and is used as a box for storing small items. The lid is usually provided at an opening of a console box body. It is rotatably mounted via a hinge shaft and a hinge arm.

SUMMARY OF THE INVENTION Among them, Japanese Patent Application Laid-Open No.
As disclosed in Japanese Patent No. 151982, there is a type in which the lid is constantly biased in the opening direction by a biasing spring pressure. However, under a console box of this type, the lid is closed and the lock is released. The lid will automatically rotate in the opening direction due to the biasing spring pressure.Taking this point alone will certainly improve usability, but on the other hand, in the process, In a case where the lid is separated from the lid, the lid pivots vigorously. Therefore, in the fully opened position, there is a sufficient possibility that the lid may be inadvertently rattled by the urging spring pressure.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of a console box of this type. A lid is provided at an opening of a console box body with a hinge shaft and a hinge arm. A lid opening / closing device for a console box, which is rotatably mounted via a connector and constantly biases the lid in an opening direction by a biasing spring pressure, comprising: a rotary damper having a braking gear; A sector gear that meshes with the braking gear of the damper is provided, and a pressing portion is provided on the hinge arm to rotate the sector gear during opening of the lid, and the sector gear is rotated by the pressing portion in response to opening of the lid. By so doing, a configuration is adopted in which the braking force of the rotary damper is transmitted to the lid.

Therefore, even in the present invention, basically,
When the lock is released under the closed state of the lid, the lid automatically rotates in the opening direction.However, while the lid rotates to the fully open position, the pressing portion on the hinge arm side is moved toward the hinge shaft side. By rotating the fan-shaped gear, the braking force obtained from the bite of the rotary damper with the braking gear,
Since the rotation speed of the lid is controlled, it is possible to effectively prevent the lid from rattling due to the urging spring pressure at the fully open position as in the related art. Therefore, it is possible to improve the texture of the opening feeling of the lid.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a console box according to a first embodiment of the present invention; It is premised on the configuration that the spring is always urged in the opening direction by the spring pressure.
By using a rotary damper fixed to the console box body side with a braking gear, the braking force is transmitted to the lid from the middle of its opening, effectively eliminating unnecessary rattling of the lid at the fully open position. It is to prevent it.

More specifically, in this embodiment, as shown in FIG. 1, a lid L is attached to a hinge shaft 1 provided on a console box body B via a bracket 2. While a torsion coil spring 3 that always urges in the opening direction is mounted, a sector gear 5 that meshes with a braking gear 4a of a rotary damper 4 is rotatably provided at one end of the hinge shaft 1 so that the sector gear 5 is rotatable. When rotated by a pressing portion 6a of a hinge arm 6 described later, the braking force of the rotary damper 4 can be transmitted to the lid L via the hinge arm 6.

As shown in FIG. 2, the sector gear 5 has a pressing portion 6a of the hinge arm 6 by hollowing out the inside in the thickness direction.
And a stopper wall 5b for abutting the pressing portion 6a of the hinge arm 6 is formed integrally with a part of the space 5a at the end side thereof. The rotary damper 4 that engages with the brake damper 4 uses braking means such as an air damper or an oil damper, and is also fixed to the console box body B via the bracket 2.

A hinge arm 6 provided on the lid L side and rotatably connected to the hinge shaft 1, as shown in FIG. A pressing portion 6a, which is located inside the lid 5a and abuts against the stopper wall 5b while the lid L is being opened, is provided by bending by 90 °, and the sector gear 5 rotated near the pressing portion 6a.
Are forcibly returned to the standby position.

Therefore, in the present embodiment, when the opening of the console box body B is closed by the lid L, as shown in FIG. 3, the sector gear 5 is a braking gear of the rotary damper 4. Although it is engaged with 4a, it does not rotate unless the lid L rotates in the opening direction.

When the lock is released in the closed state of the lid L, the lid L is rotated in the opening direction by the urging spring pressure of the torsion coil spring 3. Since the arm 6 also rotates in the same direction, the pressing portion 6a of the hinge arm 6 is moved to the stopper wall 5b of the sector gear 5 as shown in FIGS.
, The sector gear 5 is moved while rotating in the same direction as the rotation direction of the lid L.

Then, in response to the movement of the sector gear 5, the braking gear 4a of the rotary damper 4 rotates,
Since the rotational speed of the lid L in the opening direction is suppressed by the braking force of the rotary damper 4, even if the lid L is constantly urged in the opening direction, the lid L is It rotates slowly, and at its fully open position, there is no worried about rattling due to the biasing spring pressure.

Moreover, in this embodiment, since the braking force can be applied while the lid L is being opened, when the operator releases the lock by placing his arm on the closed lid L, At first, the lid L can be opened as it is by pushing up the arm by the biasing spring pressure. However, even if the arm is separated from the lid, the backlash is prevented by the biasing spring pressure at the fully open position. This can be expected to improve the feel of the opening feeling.

Conversely, when the lid L rotates in the closing direction, the hinge arm 6 also rotates in the same direction in conjunction with this, and therefore, as shown in FIG. Separated from the stopper wall 5b of the sector gear 5, the sector gear 5
Only the body itself remains in place, but as the lid L rotates, the projecting piece 7 provided on the hinge arm 6 presses the sector gear 5 as shown in FIG. 5 is forcibly returned to the standby position again.

[0015]

As described above, according to the present invention, by adopting the above configuration, basically, when the lock is released under the closed state of the lid, the lid automatically rotates in the opening direction. However, while the lid is rotating to the fully open position, the pressing portion on the hinge arm rotates the sector gear on the hinge shaft side, and the braking force obtained from the engagement with the braking gear of the rotary damper causes the lid to rotate. Since the rotation speed is controlled, it is possible to effectively prevent the lid from rattling due to the biasing spring pressure at the fully open position as in the related art. Therefore, it is possible to improve the texture of the opening feeling of the lid.
