Abstract: A block lock for connecting two chain ends is disclosed including two opposing block lock halves extending in the longitudinal direction when the block lock is in the locked state, which interlockingly engage in each other, and which lock to form at least one receiving opening for receiving a chain link. The block lock halves are pivotably coupled together in the region of a pivoting end such that the block lock halves can be shifted into an open position or locked position by performing the pivoting movement. In the locked position, the block lock halves integrally engage in one another at an opposite locking end and can be locked.

Abstract: The invention relates to a block lock for connecting two chain ends which comprises two block lock halves which extend in the longitudinal direction and which engage with each other in a positive fit via pins and grooves and lock to form two seating openings, each one to receive a chain link. The seating openings are separated by a crossbar which extends from one of the block lock halves to the opposite block lock half, wherein the block lock halves are coupled so as to rotate about the crossbar and/or on an end of a block lock half, a pin which protrudes in the direction of the opposite block lock half, which engages laterally in one lateral seating groove formed on one end of the opposite block lock half, when carrying out a relative rotational movement of both block lock halves.

Abstract: A chain connecting element has two link brackets, coupled via their limbs, and a crosspiece inserted transversally between the limbs, A limb of each link bracket has a neck section and a journal, a neck recess and a journal recess being provided on the opposite limb. The crosspiece includes a bolt, a sleeve and a spring journal. The crosspiece is a mirror-symmetrical design with an outer-lying bearing sleeve on each side of the crosspiece for form-locked locking engagement in the link brackets. The inner-lying bolt has a spring journal on each of its ends, wherein a clamping pin is insertable or extractable on both sides of the locking bolts and secures each of the spring journals in a respective bearing sleeve in form-locked manner.

Abstract: The invention relates to a chain connecting link, which has two link brackets (4, 5) coupled via their limbs (6, 9), and a bar (14a-14c) that is inserted transversely between the limbs (6, 9) of the link brackets (4, 5). One limb (6) of each link bracket (4, 5) comprises a neck section (7) and a pin (8) thicker than the neck section, and a neck recess (10) and a pin recess (11) are provided in a matching fashion at the other limb (9) of the link bracket (4, 5). According to the invention, conically configured flank surfaces (12) with respect to the vertical central longitudinal plane (MLE) are provided at each pin (8) and at each pin recess (11).

Abstract: A block connecting link for round steel chains includes two identical stirrup-like link halves each having an essentially rectangular cross-section and a rear surface without projections, planar side surfaces, convexly curved end surfaces and receiving means for round chain links located adjacent the transverse middle plane and facing the middle plane of division between the link halves. At one end of each link half is provided a projection which protrudes beyond the middle plane of division, wherein the projection includes a convex bracket protruding at a distance toward the adjacent end surface, and at the other end of the link half a projection which also protrudes beyond the middle plane of division and has a concave recess adapted to the bracket and arranged at a distance from the adjacent end surface.
