Abstract
The coupling device contains at least an orthogonal joint member, a number of connector members, and at least two oblique joint members. The orthogonal joint member has at least 6 faces, 5 of which are configured with a through hole, and a through slot and a blind trough extended from the through hole. Each connector member contains an axial pin, a wing plate on a front tip of the axial pin. Each oblique joint member is L-shaped, and each of the two outer faces of the L-shaped body is configured with a through hole, and a through slot and a blind trough extended from the through hole. A coupling column is configured behind one of the two outer faces. With the coupling device, a number of beams can be joined into a framework to be used as a storage shelf or the skeleton of a game house.
Claims4
A coupling device for joining a plurality of beams or plates, comprising:
- at least an orthogonal joint member comprising six faces, five of which are configured with a first through hole and a first through slot extended from the first through hole;
- a plurality of connector members, each comprising a face plate, an axial pin extended from a front side of the face plate, a wing plate on a front tip of the axial pin, and a plug behind the face plate having axial ribs;
- at least two L-shaped oblique joint members, each of the two outer faces of the L-shaped body configured with a second through hole and a second through slot extended from the second through hole, a coupling column configured behind one of the two outer faces;
- wherein each connector member has its plug stuffed into a beam or a channel on a plate;
- the oblique joint members are rotatably pin-joined together by their coupling columns;
- and each beam or plate is joined to an orthogonal or oblique joint member by plugging the axial pin and the wing plate of the connector member into a first or second through hole and a first or second through slot, respectively, and turning the connector member for a degree.
