Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an opening/closing device for a storage box such as a glove box, its lid, or an ashtray in the interior of a vehicle such as an automobile.

<Prior art> An inner case such as a storage box that opens downward is pivotally attached to a housing in the vehicle interior, and a centrifugal governor is attached to either the housing or the inner case, and the inner case is moved by its own weight or the weight of the contents inside. The present applicant proposed a patent application in which the movement of the storage box when opening downward is transmitted directly or to the joints of the centrifugal governor to rotate the input shaft, thereby allowing the inner case to open quietly. 59
- Proposed in No. 101827.

The movement of the inner case when it opens downwards is transmitted to the input shaft of the centrifugal governor as a rotational input via the one-way clutch, and within the governor case, the centrifugal force accompanying the rotation of the input shaft causes the input shaft to move integrally with the input shaft. The governor piece, which is pivotally attached to the rotating turntable, is swung out and slides into contact with the inner peripheral surface of the case, and its friction dampens the rotational input, allowing the inner case to open silently.

<Problems to be Solved by the Invention> In the centrifugal governor of the conventional device described above, even when the load on the inner case is small and the downward opening speed is slow, the governor piece is swung out by centrifugal force and slides into contact with the inner peripheral surface of the case. , the speed at which the inner case opens downward becomes even slower, which is frustrating.

<Means for Solving the Problems> Accordingly, the present invention pivots an inner case that opens downward to a housing in the vehicle interior, and attaches a centrifugal governor to either the housing or the inner case, thereby reducing the weight of the objects contained therein. In the opening/closing device for a vehicle interior storage box, the movement of the inner case when the inner case opens downward due to weight is directly or indirectly transmitted to the input shaft of the centrifugal governor to rotate the input shaft, A rotary disk that rotates together with the input shaft is housed in the case, and a governor piece that is oscillated by centrifugal force and comes into sliding contact with the inner peripheral surface of the case is pivotally mounted on the rotary disk, and the centrifugal force has a certain predetermined magnitude. An opening/closing device for a storage box in a vehicle interior, characterized in that an elastic regulating means is provided for pulling the governor piece so that it is not swung out until the governor piece reaches the height.

<Function> According to the above, when the load on the inner case is small and the downward opening speed is slow, the centrifugal force is smaller than the traction force of the elastic regulating member, so the governor piece is pulled by the regulating member and is not swung out, so the inner circumferential surface of the case Do not come in contact with the Then, when the load on the inner case is large, the speed at which it opens downward becomes faster, and the generated centrifugal force becomes greater than the traction force of the regulating member, the governor piece is swung out and comes into sliding contact with the inner peripheral surface of the case.

<Embodiment> 1 is an instrument panel of a vehicle body, 2 is a housing provided as a recess in the panel 1 and has an open lower surface and front surface, and 3 is a glove box or the like which is pivotally connected to the left and right side walls of the housing by a pivot 3'. The lid, other ashtrays, etc. are collectively referred to as the inner case in this book. As is well known, the inner case is opened by rotating downward about the pivot 3', and is normally held in the closed position by a fastener or lock.

Reference numeral 4 designates a centrifugal governor, which has an input shaft 7 equipped with an input gear 5. In this embodiment, the centrifugal governor is attached to a side wall 2a of the housing, and a pivot 3' is mounted on a side wall 3a of the inner case opposite to the side wall 2a. An arc-shaped rack 6 is provided at the center, and the input gear 5 of the centrifugal governor is meshed with the rack 6.

The input shaft 7 is cut into the centrifugal governor at a point protruding from the case 4' to form a base 7a and an input gear 5.
It consists of a tip part 7b to which a fixed part is fixed, and both parts 7a and 7
b is connected with a one-way clutch 8, for example, a coil spring as shown in the figure, and when the inner case 3 is opened downward, the one-way clutch 8 is connected, and when raised upward to close the inner case, it is disconnected and the input gear is connected. 5 and the tip 7b can be freely rotated.

Inside the case 4' of the centrifugal governor, there is a rotary disk 9 fixed to the base of the input shaft, and one or several arc-shaped governor pieces 10 made of metal and having a large mass are pivotally connected to the rotary disk at one end. When the inner case opens downward, the rotary disk 9 rotates via the one-way clutch 8, which is in contact with the inner case, and the centrifugal force causes the governor piece 1 to rotate.
0 is swung out so that its free end comes out of the rotary disk 9 and comes into sliding contact with the inner circumferential surface of the case, thereby damping the speed at which the inner case opens downward.

In the present invention, the governor piece 10 is pulled by an elastic regulating member 11 in a direction that resists centrifugal force.

The regulating member 11 is a coil spring in each of the illustrated embodiments, and in the embodiments shown in FIGS. It has been reduced.

Also, in the embodiment of FIG. 5, two opposing governor pieces 10, 10 are stretched between their pivot ends and their free ends. Therefore, each governor piece 10 will not be swung out from the outer periphery of the rotary disk unless a centrifugal force greater than the traction force caused by the tensioning of the coil spring is generated.

In the illustrated embodiment, the centrifugal governor is attached to the housing, but it can be attached to the inner case instead.
The gear at the tip of the input shaft may be engaged with a rack provided on the side wall of the housing. Furthermore, one end of the link is pivotally connected to the housing and the inner case, a centrifugal governor is attached to the other end of one of both links, and the tip of the input shaft of the centrifugal governor is fixed to the other end of the other link. The input shaft of the centrifugal governor may also be rotated when both links bend and extend during opening and closing.

<Effects of the Invention> As described above, in the present invention, the governor piece pivotally attached to the rotating disk of the centrifugal governor is not shaken until the centrifugal force acting on the governor piece due to the rotation of the rotating disk reaches a certain predetermined magnitude. It is pulled with an elastic regulating member to prevent it from coming out. Therefore, not only when the rotary disk is stationary, but also when the inner case opens downward, its speed increases to a certain extent,
The governor piece is not swung out of the rotating disk until the centrifugal force reaches a predetermined level. Therefore, if the opening speed of the inner case is slow, there is no need to further slow down the opening speed.

Also, even if the opening speed is high, the governor piece may violently collide with the inner periphery of the governor case, and the rebound may cause the governor piece to collide with the inner periphery of the case several times, causing unpleasant noise. It can be prevented. still,
The elastic traction force of the regulating means can be appropriately selected and set to determine how fast the inner case should open so that the governor piece is swung out.
