Mechanism for simultaneously coupling or uncoupling a plurality of heald shaft coupling devices

A mechanism for simultaneously coupling and uncoupling a plurality of heald shaft coupling devices to and from a heald shaft, comprising a coupling drive (27, 28), each of said coupling devices comprising a first coupling section (5) connectable to a heald shaft, a second coupling section (11) connectable to said coupling drive (27, 28), said first coupling section (5) comprising a plug-in member (13) including a locking surface (13A), said second coupling section comprising a socket housing (16, 17) for receiving said plug-in member (13), a first journal shaft (19) in said socket housing, a latching pawl (14) journalled to said first journal shaft (19) in said socket housing (16, 17), said latching pawl including a latching surface (14A) for engaging said locking surface (13A) of said plug-in member (13) when said plug-in member (13) is plugged into said socket housing (16, 17), a toggle mechanism (20), mounted in said socket housing (16, 17) and connected to said latching pawl (14) for moving said latching pawl (14) into an engaging and a disengaging position relative to said locking surface (13A) of said first coupling section (5), said toggle mechanism (20) comprising a tension spring (22) mounted in said socket housing (16, 17) and a three-point link (25), and wherein said coupling drive (27, 28) comprises a second journal shaft (27) mounted in said socket housing (16, 17) and an actuating member (28) journalled to said second journal shaft (27) in said socket housing, and wherein said three-point link (25) is pivoted to said latching pawl (14), to said tension spring (22), and to said actuating member (28).
