Rotation-type joggle structure and furniture having the same
Abstract:
It relates to a joggle structure and a furniture with the same. The joggle structure has a groove and a tongue cooperating with the groove. The groove has a bottom surface and two groove side faces. Width of the groove gradually increases from groove opening to the bottom surface. The two groove side faces are a part of a rotational curved surface around a rotation axis arranged in the middle of the two groove side faces. The tongue has two tongue side faces for matching with the two groove side faces, and the two tongue side faces have the same shape as the groove side faces. In the process of engaging, the tongue is rotated with respect to the groove and joggled into the groove to make the two tongue side faces attach to the two groove side faces.
