Patent ID: 8671520

Claim:
A slide assist device, comprising: a draw-in unit including: a case adapted to attach to one of a main body or a mobile body, a slider slidably placed on the case, a latch pivotally supported in the slider and capable of switching between a standby position in which the latch is locked in a corresponding portion of the case and a draw-in position in which the latch is released from the case, and an urging device connected to the slider and arranged to accumulate an urging force thereof, and an actuating member adapted to attach to the other of the main body or the mobile body, and arranged to be able to engage with the latch so that the latch is switched from the standby position to the draw-in position, or to be able to disengage from the latch so that the latch is switched from the draw-in position to the standby position, wherein when the latch is switched from the standby position to the draw-in position, the urging force accumulated in the urging device moves the mobile body from a first position on a main body side to a second position through the actuating member, wherein the latch includes an axis portion having a D-shape including a circular portion and a flat surface along an axis direction, and the slider includes an axis hole to rotatably fit the axis portion, and the axis hole having a D-shape including a circular portion corresponding to the circular portion of the axis portion and a positional control surface corresponding to the flat surface, and the draw-in unit is arranged so that when the latch is switched to the standby position, the flat surface of the axis portion and the positional control surface of the axis hole face each other, and when the latch is switched to the draw-in position, the flat surface of the axis portion abuts the positional control surface of the axis hole and prevents the axis portion from further rotation.
