Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing device for a storage unit lid, and more particularly to an opening / closing device for a storage unit lid installed in a vehicle interior of a vehicle such as an automobile.
[0002]
[Prior art]
Conventionally, an example of an opening / closing device for a storage unit lid that is installed in a passenger compartment of a vehicle such as an automobile is disclosed in Japanese Patent Laid-Open No. 5-38983.
[0003]
As shown in FIG. 14, in this storage unit lid opening / closing device, the lids 100, 102 that are manually opened are closed with respect to the rotating shafts 104, 106 and the closed position shown in FIG. It is urged by a spring 108 having two stable points at the open position shown in FIG. In addition, the spring 108 has a neutral point in the middle of the two stable points where the reaction force is larger than these stable points, and stably holds the lids 100 and 102 in the closed position and the open position. It can be done.
[0004]
[Problems to be solved by the invention]
However, in this storage unit lid opening / closing device, since the lids 100 and 102 are directly manually opened and closed, the operability is not good. As an apparatus for improving this, a configuration in which the lids 100 and 102 are opened and closed by pressing the button is conceivable. However, the lids 100 and 102 are attached to the rotating shafts 104 and 106 by a pressing operation force on the button. When it is intended to rotate, an operating force larger than the sum of the reaction force of the spring 108 and the inertia weight of the lids 100 and 102 is required. As a result, a large force is required when pressing the button, and the operability is reduced.
[0005]
In view of the above facts, an object of the present invention is to provide an opening / closing device for a storage lid that can reduce the operating force of a button when opened or closed.
[0006]
[Means for Solving the Problems]
The present invention according to claim 1 includes a rotating body interlocking with an opening / closing operation of the lid,
An urging means in which a neutral point where a reaction force is larger than a stable point is formed between the open position and the closed position of the lid body as two stable points;
An engaging portion formed on the rotating body, wherein the connecting portion of the urging means is movably engaged within a range exceeding the neutral point from the stable point of the rotating body;
A connecting portion moving means for moving the connecting portion of the biasing means from the stable point to a range exceeding the neutral point by pushing the button;
It is provided with.
[0007]
Therefore, when the button is pushed in the state where the lid is in either the open position or the closed position, the connecting portion of the urging means is formed on the rotating body via the connecting portion moving means. The inside of the engaging portion moves from one stable point of the rotating body to a position exceeding the neutral point. Thereafter, the rotating body moves toward the other stable point by the reaction force of the urging means, and in conjunction with this, the lid body moves toward the other of the open position and the closed position. As a result, the operating force of the button is expended only for the movement of the connecting portion of the urging means from the one stable point of the rotating body to the neutral point within the engaging portion formed on the rotating body. The opening / closing operation of the lid itself is performed by the reaction force of the urging means. For this reason, the operation force of a button can be reduced.
[0008]
According to a second aspect of the present invention, in the storage unit lid opening and closing device according to the first aspect, the lid is opened and closed by rotation.
[0009]
Therefore, since the lid opens and closes by rotation, if the rotation center of the lid is away from the center of gravity of the lid, the inertia weight of the lid increases when opened or closed, but the operating force of the button is The connecting portion of the urging means is spent only on the movement from the one stable point of the rotating body to the neutral point within the engaging portion formed on the rotating body, and the subsequent opening / closing operation of the lid itself Since it is performed by the reaction force of the urging means, the operation force of the button can be reduced even in the configuration in which the lid is opened and closed by turning.
[0010]
According to a third aspect of the present invention, in the opening / closing device for the storage unit lid according to the first aspect, the connecting portion moving means includes a pair for opening and closing.
[0011]
Therefore, in addition to the contents described in claim 1, since the connecting portion moving means includes a pair for opening operation and closing operation, it is possible to reduce the operating force of both the opening and closing buttons.
[0012]
