Title:
TURNBUCKLE TYPE JOGGLE STRUCTURE AND FURNITURE HAVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/067804
Kind Code:
A1
Abstract:
Disclosed in the present invention are a turnbuckle type joggle structure and a furniture having the same, and the joggle structure comprises a tongue groove (100) and a tenon (200). The tongue groove (100) is provided with a bottom face (103) and two side faces (101,102), and the width of the tongue groove (100) gradually increases from the opening (104) to the bottom (103). The two side faces (101,102) of the tongue groove are a part of a rotating curved surface. The rotation axis of the rotating curved surface is disposed in the middle of the two side faces (101,102) of the tongue groove. The tenon (200) is provided with two tenon side faces (201,202) matched with the two side faces (101,102) of tongue groove. The two tenon side faces (201,202) have the same shape as the side faces (101,102) of the tongue groove. At the time of joggling, the tenon (200) rotates with respect to the tongue groove (100) and is clamped in the tongue groove(100), thus enabling the two tenon side faces (201,202) to be attached to the two side faces (101,102) of the tongue groove. The side face of the tenon (200) of the turnbuckle type joggle structure and the side face of the tongue groove (100) are a part of the rotating curved surface, and thereby the tenon (200) and the tongue groove (100) can be buckled and disengaged only through their counter rotating. The contact area between the tenon (200) and the tongue groove (100) is larger than that of a conventional joggle structure, and thereby the joggle structure is firmer, and connection strength is increased.
