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 that opens downward is pivotally mounted to a housing in a vehicle interior, and a speed governor consisting of a centrifugal governor or a rotary damper is fixed to either the housing or the inner case, or is fixed relative to both. When the inner case opens downward due to its own weight or the weight of the contents inside, the movement of the inner case is transmitted directly or indirectly to the speed governor via the input shaft, allowing the storage box to open silently. This was proposed by the present applicant in Japanese Patent Application No. 101827/1982.

(Problem to be Solved by the Invention) In the conventional example described above, the speed governor is activated even when the downwardly opened storage box is lifted up by hand to close it, so it takes force to close it. Also, it cannot be closed quickly.

(Means for solving the problem) Therefore, the present invention divides the input shaft into a base end and a distal end, and reduces the diameter by using the input shaft between the two, which rotates when the inner case opens downward. When the inner case is closed upward, the coil spring expands in diameter as the input shaft rotates, intermittent transmission of rotation from the input shaft tip to the base end, thereby controlling the operation of the speed governor. It is characterized by having the following.

(Function) As a result, according to the present invention, when the inner case opens downward, the input gear and coil spring become stronger and the speed governor operates, and it opens silently as before, but when the inner case is closed, The input shaft idles against the coil spring and can be closed without activating the speed governor.

(Example) l is the instrument panel of the vehicle body, λ is the above panel/
3 is a glove box serving as an inner case which is pivoted to the left and right side walls of the housing with a pivot 3', and as is well known, the glove box faces downward with the pivot 3' as a fulcrum. It pivots open and is normally held in the closed position by a clasp or lock.

Hiro is a speed governor consisting of a centrifugal governor or a rotary damper, and in any case has an input shaft equipped with an input gear 5,
Any device that attenuates or brakes the rotational input transmitted to the input gear j may be used.

The centrifugal governor is described in the aforementioned Japanese Patent Application No. 59-101827, although it is not limited thereto, and the rotary damper is similarly described in the Japanese Patent Application No. 59-101, although it is not limited thereto.
Please refer to No. 01828 for a detailed explanation.

In this embodiment, the speed governor≠ is connected to the side wall λα of the housing.
The side wall 3α of the inner case facing the side wall λα is provided with an arc-shaped rack 6 centered on the pivot 3', and the input gear 5 of the speed governor Hiroshi is meshed with the rank B.

The input shaft 7 of the speed governor is separated at a point where it projects outward from the device, and the base end 7α that projects from the device and the tip 7b to which the input gear S is attached are connected by a one-way clutch.

In this embodiment, the one-way clutch has a coil spring t having an inner diameter slightly smaller than the outer diameter of the input shaft 7, and the base end 7α of the input shaft is inserted into the fill spring from one end, and the tip end 7b is inserted into the fill spring from the other end. A fill spring is inserted from each end with its diameter enlarged, and the winding direction of the fill spring is such that the inner case 3 rotates downward and opens, and the rack 6 becomes an input gear with that movement! When a rotational input is transmitted to the distal end portion 7b and the distal end portion 7b rotates as a unit, the winding diameter is reduced by the frictional force caused by the rotation.

Therefore, when the inner case 3 rotates downward, the fill spring reduces its winding diameter and firmly grips the base end 7α of the shaft from around it, so that the inner case opens quietly by the speed governor. Next, when the inner case that has been opened is raised up and closed again, the input gear 7 and the shaft tip 7b rotate in the opposite direction due to this movement, and the winding diameter of the coil spring is expanded by frictional force. , the tip 7b slips and rotates in the coil spring and does not transmit the closing movement of the inner case to the speed governor. Therefore, the inner case can be easily closed by hand.

In the above embodiment, the inner diameter of the coil spring was made slightly smaller than the outer diameter of the input shaft, but this was done in order to constantly apply a frictional force between the input shaft and the coil spring. The inner diameter of the coil spring may be larger than that of the input shaft as long as the rotation from the input shaft is reliably transmitted to the coil spring, such as by bending it toward the input shaft and locking it to the input shaft.

Furthermore, although the speed governor is fixed to the housing in this embodiment, it may instead be fixed to the inner case and the gear at the tip of the input shaft meshed 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 speed governor is fixed to the other end of one of both links, and the tip of the input shaft of the speed governor is fixed to the other end of the other link. ,° Both links may be bent and stretched by opening and closing the inner case.

In this case, a coil spring is wound and inserted between the tip of the input shaft of the speed governor and the other end of the other link, and when the inner case is opened, the coil spring is contracted in diameter to operate the speed governor, but when the inner case is closed, the coil spring is wound and inserted. Expands the diameter of the coil spring and deactivates the speed governor.

(Effects of the Invention) As is clear from the above, in the present invention, when the inner case opens downward, the movement is performed quietly by the speed governor, and conversely, when the inner case is raised upward and closed, the speed is controlled. It can be closed quickly and easily without activating the device, and
If the speed governor operates even when closing, there will be no situation where the inner case is forcibly closed and the speed governor is damaged in an attempt to quickly close it.
