Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid delay operation mechanism that can be automatically closed after a lapse of a predetermined time after manually opening a lid of an accessory case disposed in a room of an automobile or the like.

Conventionally, a storage mechanism such as an accessory case with a lid has been opened until it is manually closed once the lid is opened, and it has a poor appearance and obstructs peripheral devices and switch operations.
For example, in the case of the lid opening / closing structure disclosed in Patent Document 1, the lid body includes a box body, a lid body that opens and closes the opening of the box body, and a biasing spring that biases the lid body in the closing direction. This consists of a contact part that is a decelerating means that decelerates the closing operation of the lid before the closing operation is completed, and a contacted part that contacts the contact part.

Japanese Patent Laid-Open No. 9-267697

However, the conventional lid opening / closing structure manually opens and closes the lid manually, and the operation is complicated, and the inside of the lid can be seen from the opened lid. In addition to the poor external appearance, there was a drawback that it interfered with peripheral devices and switch operation.
In addition, the structure of the lid that can be automatically closed after a predetermined time has elapsed by a timer or electrical control is possible, but there is a problem that the structure becomes complicated and the number of parts increases and cannot be provided at low cost.

  This invention has been made to solve the above-mentioned inconveniences. When a lid is manually opened and small items are stored inside or taken out, the automatic operation is automatically performed after a predetermined time has elapsed. A lid delay operation mechanism capable of closing a lid is provided.

The present invention has the following contents.
(1) The lid body delay operation mechanism of the present invention includes a storage case main body, a lid body that can be opened and closed, and one end attached to the lid body, and the other end of the storage case body. An arm member pivotally supported by the case body, a cam member that rotationally drives the arm member via a pin member provided upright, a spring member that urges the cam member to rotate, and one end thereof A lever member that is pivotably locked to the arm member and has the other end in contact with the cam member, and a damper member that engages with a part of the cam member to reduce the rotation speed of the cam member And a rail member that guides a lever pin erected on the other end of the lever member. After the lid body is manually opened, when the hand is released from the lid body, the cam member may return and rotate. The pin member erected on the cam member is the arm. Time until it abuts against the timber, and wherein the lid is closed after maintaining the open state.
(2) In the lid delay operation mechanism according to (1), when the lever pin is detached from the rail member, the cam member slowly returns and rotates by the biasing force of the spring member and the action of the damper member, The closing operation of the lid is stopped for the time until the pin member comes into contact with the arm member.
(3) In the lid delay operation mechanism according to (1) or (2), the rail member is composed of two curved members, and holds and guides the lever pin from the closed state to the open state. Then, the guide of the lever pin is finished when the opening operation of the lid is completed.
(4) In the lid body delay operating mechanism described in (1) to (3), the damper member is a rotary damper and is in mesh with a part of the cam member.
(5) In the lid delay operation mechanism according to (1) to (4), the cam member is not rotated by the spring member while the rail member sandwiches and guides the lever pin. When the engagement is disengaged, the lid is rotated and the lid is closed via the arm member.

According to the lid delay operation mechanism of the present invention, the storage case main body, the lid disposed so that the opening of the storage case main body can be opened and closed, one end is attached to the lid, and the other end is the storage case An arm member pivotally supported by the main body, a cam member that rotationally drives through a pin member that is erected on the arm member, a spring member that urges the cam member to rotate, and one end of which is A lever member that is pivotally locked to the arm member and has the other end in contact with the cam member; and a damper member that engages with a part of the cam member to reduce the rotational speed of the cam member; A pin member that is erected on the cam member when the lid closes the opening of the storage case body. Abuts part of the arm member As the cover body is urged in the closing direction and the cover body is manually opened, the lever pin of the lever member rotates the cam member greatly in the counter-biasing direction while being guided by the rail member, When the opening of the lid is completed, the lever pin is detached from the rail member and the cam member can be rotated back. When the hand is released from the lid, the lever pin stands up against the cam member even if the cam member returns and rotates. Since the open state is maintained for a time until the provided pin member comes into contact with the arm member, the lid is opened while an object is taken in and out of the storage case, and is automatically closed after a predetermined time.
In other words, the lever member can create a delay time by rotating the cam member to increase the rotation angle of the cam member.
Therefore, it is easy to operate, and there is no possibility of seeing an object housed inside from the opened lid, which does not obstruct peripheral devices or switch operation.
Further, the cam member slowly rotates back by the biasing force of the spring member and the action of the damper member when the lever pin is detached from the rail member, and the time until the pin member contacts the arm member, Since the closing operation is stopped, the lid can be kept open for a predetermined time.
Therefore, it is possible to secure time for taking in and out the storage case.
The shaft body can be securely held and fixed.
The rail member is composed of two curved members, holds and guides the lever pin from the closed state to the open state, and ends the guidance of the lever pin when the opening operation of the lid is completed. Therefore, in the middle of the process of opening the lid, there is no fear that the lid will be closed, and the lid can be closed only after the opening operation is completed.
The shaft body can be securely attached to the attached member via the lid delay operation mechanism.
Further, since the damper member is a rotary damper and meshes with a part of the cam member, the return rotation of the damper member can be delayed and the open state of the lid can be maintained for a predetermined time. .
Further, the cam member does not rotate by the spring member while the rail member clamps and guides the lever pin, and rotates when the rail member and the lever pin are disengaged to cover the cam member via the arm member. Since the body is closed, there is no possibility that the lid will be closed during the process of opening the lid, and the lid can be closed only after the opening operation is completed.
