Field of the Invention The present invention relates to a pop-up mechanism suitable for use in an armrest, a height-adjustable armrest, etc., which is constructed on a center console box of an automobile. The present invention relates to a pop-up mechanism that attaches an elevating body to a column provided in the column and raises or lowers the elevating body by raising or lowering the column.

[0002]

2. Description of the Related Art Conventionally, a lid of a center console box of an automobile is provided with an elevating body that can be raised and lowered by operating a button, and an openable and closable lid that closes the console box is raised to raise an armrest (armrest). It is also possible to use it as).
It is proposed in Japanese Patent No. 6638.

That is, Japanese Utility Model Laid-Open No. 3-26638 discloses that
A lifting unit is attached to a support rotatably provided on a base body, and a pop-up unit that raises or lowers the lifting body by raising or lowering the support column is used. It is shown that the lid body of the center console box is used as an armrest while being fixed to the lid body of the above, and an armrest body provided with a cushioning material and the like is attached to the lifting body.

The pop-up unit disclosed in Japanese Utility Model Laid-Open No. 3-266638 will be described in detail. In this pop-up unit, a plurality of columns are rotatably mounted on the upper surface of a base body, and the column is lifted up and down at the tip of the column. The body is rotatably attached, and the torsion spring attached to the connecting portion between the tip of the column and the elevating body urges the column upright, and the column is rotated by the urging force of the torsion spring. It is made to stand up and the lifting body is raised.

Further, the support column is rotated by the urging force of the torsion spring, and is in a rotation limit in a state of abutting against the locking body and standing up.

[0005]

However, in the pop-up unit disclosed in Japanese Utility Model Laid-Open No. 3-26638, when the elevating body is lifted and used as an armrest, the force applied to the elevating body and the base body are applied. There is a problem in that this portion is apt to be damaged because it is concentrated on the shaft that rotatably connects the support.

That is, in this pop-up unit, as shown in FIG. 32, the pillar a is a locking body in which the rotational movement L by the urging force of the torsion spring b is provided in the vicinity of the connecting portion of the base c with the pillar a. It is designed to stop when the support pillar a is in contact with d, but in this case, most of the force F applied to the elevating body e is applied to the shaft f that rotatably connects the base body c and the support pillar a. concentrate. Further, the support a is slightly inclined forward (on the side where the locking body d is disposed), and the locking body d is
Since it abuts on the base end of the support, the support a is a lever with the contact point between the locking body d and the support a as a fulcrum, and a very large force is concentrated on the axis f. For this reason, inconvenience such as damage is likely to occur at the connecting portion between the support a and the base c.

The present invention has been made in view of the above circumstances, and the base body and the elevating body are connected by a plurality of rotatable columns,
An object of the present invention is to provide a pop-up mechanism in which the force applied to the lifting body is prevented from being concentrated at one point by improving the prop structure of the pop-up mechanism that biases the prop in one rotation direction.

[0008]

In order to achieve the above-mentioned object, the present invention provides a base body, a plurality of support posts having one end hinged to the upper surface of the base so as to be able to rise and fall, and the other end portion of the support post. An elevating body hinged to, a biasing means for biasing the column in one rotation direction, and a projecting member provided on the upper surface of the base body to abut the column to stop the pivotal movement of the column. The column comprises a locking body for holding the column upright on the base, and a lock mechanism for locking the column upright on the substrate and upright on the substrate. From the folded state, the locked state by the lock mechanism is released, the support is rotated by the biasing means, and the support is brought into contact with the locking body to stand up, so that the lifting body is lifted from the base body. In the pop-up mechanism that allows the locking body to have a trapezoidal shape, In this state, a locking portion having a locking step is provided on the base end side of the supporting column, and the locking step of the locking portion abuts on the upper surface of the trapezoidal locking body to raise the supporting column. A pop-up mechanism is provided that is configured to be retained in the.

In this case, as a preferred embodiment of the present invention, the lock mechanism includes the first locking means for mutually locking the upper end of the column and the lifting body, and the base body and the lifting body. A pop-up mechanism composed of a second mutual locking means for locking, and a substantially plate-bar-shaped rising auxiliary body that is hinged on the upper surface of the base body and is urged upward, are provided from the folded state to the locked state. There is provided a pop-up mechanism in which the rising auxiliary body pushes up the lifting body when releasing the lifting body so as to assist the initial rising motion of the column.

[0010]

According to the pop-up mechanism of the present invention, the support attached to the base body is rotated by the urging force of the urging means to stand up, and the lifting body attached to the tip of the support is raised. In this case, the pivotal movement of the column is stopped when the column abuts against the locking body and stands up, and the pivotal movement of the column is locked by the lock mechanism from the state where the column is laid down on the base and folded. Start by releasing the state,
In a state in which the support column is erected and the lifting body is raised, the pillar is locked again by the lock mechanism and the lifting body is held in the raised state. Then, by releasing the locked state by the lock mechanism from the state where the supporting column is erected to raise the elevating body and pressing the elevating body, the supporting column is rotated against the urging force of the urging means, and the elevating body is moved. It is possible to return to the initial state by lowering and folding, and locking with a lock mechanism.

In this case, according to the pop-up mechanism of the present invention, when the support pillar is rotated from the tilted state to the upright position, the locking step of the locking portion formed on the base end side of the support pillar is provided. Since it comes into contact with the upper surface of the trapezoidal locking body protrudingly provided on the upper surface of the base body, even if a large load is applied to the lifting body that is lifted and locked, the load is on the locking body and the strut. And the connection portion between the base and the base. Therefore, it is possible to prevent the load applied to the lifting body from being concentrated on the connecting portion between the support column and the base body and damaging the connecting portion as much as possible, so that a large load may be applied to the lifting body. Is also preferably used.

Further, the lock mechanism is composed of first locking means for mutually locking the upper end of the column and the lifting body and second mutual locking means for mutually locking the base body and the lifting body. By so doing, when the pillar is raised and the lifting body is lifted, the pillar is locked by the first mutual locking means to reliably hold the lifted state of the lifting body, and when the pillar is folded and folded, the second pillar is held. The mutual lock means directly locks the base body and the lifting body, so that the folded state can be reliably maintained without rattling.

Further, by providing a rising assisting body for pushing the elevating body upward on the upper surface of the base body, the locked state by the lock mechanism is released from the folded state in which the support column is folded on the base body, and the urging force of the urging means. When rotating the pillar with and raising the lifting body, the initial initial movement of the pillar is assisted,
It is possible to reliably activate the lifting movement of the lifting body.
