Description

Button holding structure

The present invention relates to a button holding structure including an operation button that is rotatably held by a holder and a spring that biases the operation button rotated by a pressing operation so as to return to a fixed position.

A monitor device installed on a ceiling surface in a vehicle such as RSE (Rear Seat Entertainment) is provided with a remote control (remote control) for operating the device.
Here, in a monitor device such as RSE, the remote controller may also serve as the operation panel itself of the monitor device. If the remote controller is lost, the monitor device cannot be operated. For this reason, in such a monitor device, a remote control holding mechanism is employed in which the remote control is assembled to the main body (holder), the remote control is exposed from the main body when in use, and the remote control is stored in the main body when not in use.

In this remote control holding mechanism, the main body has a storage recess for storing the remote control. One end side of the remote controller is rotatably connected to one end side of the storage recess. In addition, a movable portion having a locking projection protruding from the side wall of the storage recess so as to lock the other end of the remote control is provided on the other end side of the storage recess. This movable part is connected with the operation button assembled | attached to the main-body part.
On the surface of the operation button, an operation surface to be pressed when the user uses the remote control is provided. In addition, rotation shafts are provided at both ends on one end side (opposite side of the housing recess side) of the back surface (main body side) of the operation button. The rotating shaft portion is provided with a bearing-side shaft portion that is fitted and held in a bearing hole provided in the bearing portion of the main body portion. Further, at the end of the rotation shaft portion, a pressing portion is provided that is connected to the movable portion and slides the movable portion in a direction to release the remote control lock by pressing the operation surface. In addition, a spring that urges the operation button so that the operation button rotated by the pressing operation returns to a fixed position is attached.

In the remote control holding mechanism configured as described above, the user presses the operation surface when using the remote control. As a result, the operation button rotates toward the main body with the bearing side shaft as a fulcrum. Then, as the operation button is rotated, the pressing portion is also rotated, and the movable portion is slid in a direction for releasing the remote control lock. As a result, the locking projection is inserted into the side wall of the storage recess, and the locking of the remote control is released, and the remote control rotates in the opening direction with one end side as a fulcrum and is exposed from the main body.
When the pressing operation on the operation button is released, the operation button is urged and rotated by the spring so as to return to the home position. As the operation button rotates, the pressing portion also rotates, and the locking projection protrudes from the side wall of the storage recess.

Another example of a button holding structure including an operation button that is rotatably held by a holder and a spring that biases the operation button rotated by a pressing operation so as to return to a fixed position is disclosed in Patent Literature There exists a structure as disclosed in FIG. In this structure, a double torsion spring is used to bias a tilting arm (corresponding to an operation button) fixed to a unit base (corresponding to a main body).

However, the dimension from the tip of one bearing side shaft provided on the operation button to the tip of the other bearing side shaft is determined from the outer surface of one bearing provided on the main body to the outside of the other bearing. Narrower than the wall. Therefore, when assembling the operation button to the main unit, slide the operation button to the bearing part side with the operation surface or bearing part bent so that the bearing side shaft part can get over the bearing part. It is necessary to engage the side shaft portion with the bearing hole. Therefore, in order to obtain the amount of bending required for assembly, a considerable length is required for the portion to be bent (operation surface or bearing portion), and there is a problem that it is difficult to secure a space. Further, when a considerable length cannot be secured in the portion to be bent, the amount of bending is reduced. Therefore, it is necessary to reduce the amount of engagement between the bearing-side shaft portion and the bearing hole. For this reason, there has been a problem that the operation button assembled to the main body portion is easily detached from the main body portion.

In the structure disclosed in Patent Document 1, since the double torsion spring is used for fixing the tilting arm to the unit base, the configuration is completely different and it cannot be applied to the operation button holding structure.

The present invention has been made to solve the above-described problems. When the operation button is assembled and held in the holder, the operation surface or the bearing portion is assembled without bending the operation surface or the bearing portion. It is an object of the present invention to provide a button holding structure capable of reducing the size of the operation button and preventing the assembled operation button from being detached from the holder.

The button holding structure according to the present invention includes a shaft portion serving as a rotation fulcrum of the operation button held in the holder, and a shaft formed when the operation button is assembled to the holder, formed in a direction different from the movable direction of the operation button held in the holder. The portion has a groove for sliding, and when the shaft portion slides to the holding position, the shaft portion is provided with a bearing groove portion for holding the shaft portion as a rotation fulcrum of the operation button.

According to this invention, because it is configured as described above, when assembling and holding the operation button on the holder, the operation surface and the bearing portion can be reduced by assembling without bending the operation surface or the bearing portion, Further, it is possible to prevent the assembled operation button from being detached from the holder.
