Description

  The present invention relates to a door device.

  As a door device in which an operation handle serving as a handle at the time of opening and closing operation is arranged without forming a concave portion for handling on the peripheral edge, a door device described in Patent Document 1 is known. In this conventional example, the operation handle is held in a housing posture along the outer surface of the door base when not in use, and is pulled out from the outer surface of the door base during use, that is, when the door base is opened.

The door base is unlocked and unlocked by a user's wireless unlocking operation, and the operation handle is shifted to a use posture by using an appropriate actuator along with the wireless unlocking operation.
Japanese Patent No. 3165570

  However, in the above-described conventional example, the door base does not require a recessed portion for handling, and therefore when the operating handle is in the stowed position, the outer surface of the door base is not uneven, and the surface of the door device is clean. Although there is an advantage that the design can be made, there is a disadvantage that the structure becomes complicated because it is necessary to configure the interlocking means with the locking / unlocking means.

  The present invention has been made to solve the above drawbacks, and provides a door device with a simple structure and capable of pulling out an operation handle when necessary without forming a handle recess for pulling out the operation handle. With the goal. Another object of the present invention is to provide a handle device that can be used for the door device.

  The operation handle 3 held by the door base 1 is a retracted posture in which the handle portion 2 having an elongated shape follows the outer surface of the door base 1 and is a handle when the door base 1 is opened and closed by being pulled out of the door base 1. It can be rotated between the use posture and the transition from the retracted posture to the use posture is performed by pushing down one end of the handle portion 2. The operation handle 3 is pivotally supported at a position where the opposite end is lifted by the pressing operation of the handle 2, and is shifted to a use posture by pulling out the other end lifted as a handle.

  Therefore, in this invention, since the operation handle 3 can be shifted from the retracted position to the use position by pressing the handle portion 2, a handle recess is provided on the surface of the door base 1 in order to pull out the operation handle 3 from the retracted position. There is no need to form. As a result, the degree of freedom in designing the surface of the door base 1 is improved.

  Further, since the posture change of the operation handle 3 is performed by a pressing operation to one end of the handle portion 2, the structure is simplified.

In order to configure the above door device,
A handle base 6 fixed to the door base 1;
An operation handle 3 having an elongated handle portion 2 that provides a handle for opening and closing the door base 1 and is rotatably connected to the handle base 6. When not in use, the handle portion 2 takes a retracted position along the door base 1. When,
A locking / unlocking operation switch 4 which is held by the handle base 6 and locks / unlocks the door base 1;
The operation handle 3 can be a handle device that can be used as a handle by pulling out the other end that is lifted by a pressing operation to one end in the longitudinal direction of the handle portion 2 in the retracted position.

  In this case, when the locking / unlocking operation switch 4, the pressing operation end of the handle portion 2, and the lifting end of the handle portion 2 are arranged in a substantially straight line in this order, first, the locking / unlocking operation switch 4 is pressed to unlock the locking device. Next, after the finger is moved and the pressing end of the handle portion 2 is pressed, the lifted end can be gripped and the operation handle 3 can be operated to improve the operability.

  According to the present invention, since the operation handle can be pulled out when necessary without forming a handle recess for pulling out the operation handle, the degree of freedom in designing the door base can be increased.

  An embodiment of the present invention configured as an automobile door is shown below in FIG. The automobile door has a door panel structure (door base 1) formed by joining the inner panel 1a and the exterior panel 1b in a bag shape and fixing a door trim (not shown) to the inner panel 1a as necessary.
