Shoulder Joint

Detail: Shoulder Joints are extensively utilized in furniture featuring frame elements, such as the integration of legs, aprons, waist rails, and wooden boards. This configuration is typical in square tables, girdled tables, square frames, and elongated frames with girdles. On the upper portion of the legs, two distinct tenons—one long and one short—are crafted to fit into the corresponding mortise holes. This design principle endows the furniture with enhanced stability and durability, equipping it to endure prolonged usage and bear significant weight.

Process: In the Shoulder Joint, just beneath the waist area, a 45° bevel is cut, and a triangular mortise is meticulously chiseled out to accommodate the faceplate's corresponding 45° angled triangular tenon. The shoulders of the joint are equipped with dovetail pins, tapered from a narrow top to a wider bottom, positioned either at the front or the back. These pins slide into grooves on the rear side of the boards, guaranteeing a tight and secure connection among the boards, the waist, and the table's legs and base. The pin openings are slightly tapered inward, ensuring that, upon installation and tightening of the boards, they are further anchored in place to resist loosening. This connector is designed to firmly lock the board in place, both horizontally and vertically, ensuring structural integrity.
