Description of the Related Art Conventionally, an elevating body which moves up and down by a button operation is provided on a lid of a center console box of an automobile, and an openable / closable lid for closing a console box is raised by raising the elevating body to provide an armrest (armrest). )) Can be used as well.
6638 publication.

That is, Japanese Utility Model Laid-Open Publication No. 3-26638 discloses that
Using a pop-up unit that attaches an elevating body to a post rotatably provided on the base and raises or lowers the post by raising or lowering the post, a base box of this unit is used as a console box. It is disclosed that an armrest body provided with a cushioning material or the like is attached to the elevating body, and the lid of the center console box is used as an armrest.

The pop-up unit disclosed in Japanese Utility Model Laid-Open Publication No. 3-26638 will be described in detail. This pop-up unit has a plurality of columns rotatably mounted on the upper surface of a base, and furthermore, the column is raised and lowered at the tip of the column. The body is rotatably mounted, and the torsion spring attached to the connection between the tip of the support and the elevating body urges the support in the direction in which the support is raised, and the support is rotated by the biasing force of the torsion spring. Then, the elevating body is raised. Then, the lock mechanism is configured to lock the elevating body in a state in which the elevating body is at the limit of elevating and the erecting body is in the state of the descent limit by erecting the supporting column.
In addition, the support column is rotated by the urging force of the torsion spring, and is limited in rotation in a state in which the support column stands in contact with the locking body.

[0005]

However, in the pop-up unit disclosed in Japanese Utility Model Application Laid-Open No. 3-26638, when the elevating body is raised and used as an armrest, the force applied to the elevating body is reduced by the base body. There is a problem that it concentrates on the shaft that rotatably connects the support and the column, and this portion is easily damaged.

That is, in this pop-up unit, as shown in FIG. 32, the column a is a locking member whose pivoting operation L caused by the urging force of the torsion spring b is protruded in the vicinity of the connecting portion of the base c with the column a. 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 c and the pillar a. concentrate. Further, the support a is slightly inclined forward (on the side where the lock d is provided), and the lock d is supported by the support a.
, The strut a becomes a lever with the contact point between the locking body d and the strut a as a fulcrum, and a very large force is concentrated on the shaft f. For this reason, inconveniences such as breakage are likely to occur in the connecting portion between the column a and the base c.

The present invention has been made in view of the above circumstances, and connects a base and an elevating body with a plurality of rotatable supports,
It is an object of the present invention to provide a pop-up mechanism in which the strut structure of a pop-up mechanism that urges the post in one rotation direction is improved so that the force applied to the elevating body is not concentrated at one point.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a base, a plurality of columns having one end hinged to the upper surface of the base so as to be capable of falling, and the other end of the column. An elevating body hinged to the support, an urging means for urging the support in one rotation direction, and a protrusion protruding from the upper surface of the base, abutting the support to stop the rotation of the support, and A locking mechanism that holds the support upright on the base; and a lock mechanism that locks the support upright on the base and the support upright on the base. The lifting state is lifted from the base by releasing the locked state by the locking mechanism from the folded state, rotating the support by the urging means, and abutting the support against the locking body to stand up. In the pop-up mechanism, the locking body is formed in a trapezoidal shape. A locking portion having a locking step on the base end side of the column, the locking step of the locking portion abutting on the upper surface of the trapezoidal locking body, and the column is standing upright. And a pop-up mechanism characterized in that the pop-up mechanism is held.

In this case, as a preferred embodiment of the present invention, the lock mechanism comprises a first mutual locking means for mutually locking between the upper end of the column and the elevating body, and a mutual interlock between the base and the elevating body. A pop-up mechanism comprising a second interlocking means for locking the upper surface of the base member, and a substantially plate-shaped rising auxiliary member which is hinged on the upper surface of the base and urged upward. A lifting mechanism is provided in which the rising auxiliary body pushes up the elevating body when lifting the elevating body by releasing the lifting force, thereby assisting the initial rising movement of the column.

[0010]

In the pop-up mechanism of the present invention, the column attached to the base is rotated by the urging force of the urging means to be erected, and the lifting body attached to the tip of the column is raised. In this case, the pivotal movement of the column stops when the column abuts on the locking body and stands up, and the pivotal motion of the column is locked by the lock mechanism from the state where the column is folded down on the base. Start by releasing the state,
In a state in which the column is raised and the elevating body is raised, the elevating body is locked again by the lock mechanism and is held in the ascended state. Then, by releasing the locked state by the lock mechanism from the state in which the column is raised and the lifting member is raised, and pressing the lifting member, the column is rotated against the urging force of the urging means, and the lifting member is rotated. Is lowered to be folded and locked by a lock mechanism, thereby being able to return to the initial state.

[0011] In this case, according to the pop-up mechanism of the present invention, when the column is turned upright from the state of falling on the base, the locking step of the locking portion formed on the base end side of the column is reduced. Since it comes into contact with the upper surface of the trapezoidal locking body protruding from the upper surface of the base, even if a large load is applied to the lifted and locked elevating body, the load is applied to the locking body and the column. And a connection part between the base and the base. Therefore, it is possible to prevent the load applied to the elevating body from being concentrated on the connecting portion between the column and the base and to damage the connecting portion as much as possible. It is also preferably used.

The lock mechanism comprises a first locking means for mutually locking between the upper end of the column and the elevating body, and a second mutual locking means for mutually locking between the base and the elevating body. By doing so, when the elevating body is raised by erecting the support, the first interlocking means locks the support by the first mutual locking means to securely hold the elevating body, and when the support is folded down and folded, the second elevating body is in the second position. The mutual locking means can directly lock the space between the base and the elevating body, so that the folded state can be reliably maintained without rattling.

Further, by providing a rising auxiliary body for pressing the elevating body upward on the upper surface of the base, the locking state by the lock mechanism is released from the state in which the support pillar is folded down on the base and folded, and the urging force of the urging means is provided. When the column is rotated by and the elevating body is lifted, the initial rising motion of the column is assisted,
The ascent and descent of the elevating body can be reliably started.
