Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lid opening/closing device for an accessory box formed in a vehicle instrument panel or the like.

(Prior Art) As shown in FIGS. 3 and 4, a conventional accessory box 2 is formed on an instrument panel 1 of a vehicle, and a lid 3 is pivotally attached to a shaft 4 at the upper rear end of the accessory box 2. , a protrusion 3a protruding from one side of the lid 3
is arranged so as to be able to rotate along the surface of the left side wall 2a of the accessory case box 2, one end of the helical spring 5 is fixed to a pin 6 protruding from the side wall 2a, and the other end is attached to the protruding piece 3a. Lid opening and closing devices for fixed vehicle storage boxes are known.

(Problem to be solved by the invention) In the above conventional device, while the lid is rotating, the pressing force of the helical spring applied to the lid is reversed, and the spring force causes the lid to snap into the closed or open position. Since the lid is pressed down, there is a problem in that the closing sound generated when closing the lid is harsh on the ears. Therefore, for example, the shaft that rotates in conjunction with the opening and closing of the lid is
It has been considered to provide a damper as shown in Japanese Patent No. 56002, but there was a problem in that the damper was applied not only when the lid was closed but also when the lid was opened, making it difficult to open the lid.

The present invention was developed with a focus on these problems, and uses a helical spring to reverse the pressing force of the spring while the lid is rotating, acting in the opening or closing direction to open and close the lid. It is an object of the present invention to solve the above-mentioned problems by providing a lid opening/closing device that performs a braking action only when the lid is closed.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention aims at reversing the pressing force of the spring installed on the lid during the rotation of the lid which is pivotally connected to the lid so that it can be opened and closed. The lid opening/closing device for a vehicle storage box that presses and holds the lid in the open/closed position includes a pressing arm that rotates as the lid opens and closes, one end supported by the side wall of the box, and the other end attached to the pressing arm. An elastic body is provided that exerts an elastic force on the pressing arm when pressed against the pressing arm, and when the pressing arm rotates in the lid closing direction, the elastic force of the elastic body increases. It is something to do.

Hereinafter, a detailed description will be given based on examples. 1
0 is an accessory box formed on the instrument panel of a vehicle, with a lid 1 attached to the shaft 11 at the top of the rear end.
2 is pivotally mounted, and a pressing arm 13 is mounted below one side of the lid 12.
are fixed together. Reference numeral 14 denotes a leaf spring as an elastic body, the lower end of which is fixed to a pin 15 protruding from the box side wall 10a, and an engaging pin 16 protruding from the side of the tip of the pressing arm 13 is brought into contact with one side of the leaf spring 14 and pressed. When the arm 13 rotates downward, the engagement pin 15 resists the elasticity of the leaf spring 14 and slides downward from above while expanding the leaf spring to the left. . Reference numeral 17 denotes a helical spring, one end of which is fixed to the pressing arm 13 and the other end fixed to a pin 18 protruding from the box side wall 10a.

Next, the effect will be explained. When the lid 12 is rotated downward from the open state shown in FIG. 1, the engagement pin 16 expands the leaf spring 14 against its elasticity and slides downward. As the closing operation of the lid progresses, the helical spring 17 rapidly reverses its direction of pushing the press arm 13 upward, and the press arm 13 is pushed downward. This pressing force tends to speed up the closing operation of the lid, but the point of contact between the engagement pin 16 and the plate 14 is gradually reduced by the plate spring 14.
As it approaches the pin 15 which is the fulcrum of the press arm 13, the braking action by the elasticity of the leaf spring 14 which attempts to return the pressing arm 13 to its original position gradually increases, and the lid 12 slowly descends to the closed lid position shown in FIG. Retained.

Next, when the lid 12, which is in the closed lid position shown in FIG.
It is pushed upward by the elastic force of 4 and rotates slightly, and during the rotation, the pressing direction of the helical spring 17 is rapidly reversed, and the pressing arm 13 is pressed upward and held in the open position shown in FIG. .

(Effects) According to the present invention, during the rotation of the lid pivotally mounted to open and close, the pressing force of the spring installed on the lid is reversed, so that the spring presses and holds the lid in the open/closed position. In a lid opening/closing device for a storage box, there is a pressing arm that rotates as the lid is opened and closed, one end of which is supported by a side wall of the box, and the other end of which is in pressure contact with the pressing arm, thereby exerting an elastic force on the pressing arm. When the pressing arm rotates in the direction of closing the lid, the elastic force of the elastic body increases, so when the lid is opened, the lid can be opened easily without any braking action. When the lid is closed, a braking action is performed, and even if the action of the helical spring is reversed during lid rotation and acts in the lid closing direction, the lid can be closed without impact. Moreover, since the structure is extremely simple, it can be provided at low cost.
