Description

  The present invention relates to a sliding door opening / closing assist device that captures and moves the sliding door to the final position when the sliding door is opened or closed and approaches the final position of the opening or closing door. .

  A slide that is slidable in the opening / closing direction of the sliding door on the upper edge door frame of the sliding door and a pin attached to the sliding door that is pivotally attached to the sliding door and close to the door frame on the closed side is received and captured. And a spring member that moves the slide toward the door frame on the closed side while the pin is captured by the hook, contacts the sliding door to the door frame on the door side, and completes the door closing of the door. A mechanism (door closer) including a damper (decelerator) that applies braking to the movement of the sliding door toward the frame is known (for example, see Patent Document 1). This mechanism ensures that the sliding door is closed just by moving the sliding door to near the door frame on the closing side, but this mechanism is provided near the door frame on the opening side to catch the sliding door that is opened. It can also be used to open the door. In this specification, it will be called a sliding door opening / closing assisting device in the meaning of a device used to ensure that the door is opened or closed.

  Although the sliding door opening / closing assisting device has the above-described function, when the sliding door is opened and closed vigorously, braking by the damper acts suddenly, and the sliding door may be rebounded by the action. When such a rebound occurs and the sliding door returns to the position where the pin is received by the hook, the hook that captured the pin is returned to the position where the pin is released, so that the sliding door returns to its original direction. As a result, proper opening / closing may not be performed.
